Guest Reviews

• letgoav (8/5): - Mi è piaciuta la comodità e il confort di una casa durante il nostro viaggio a Kyoto per 1 settimana, spaziosa ed attrezzata. Comodissimo il letto, si dormiva davvero bene. Non mi è piaciuto il fatto che mancassero le mollette per stendere i panni, c'erano solo le grucce, c'era poco detersivo per piatti e per la lavatrice, (è bastato giusto giusto per il nostro soggiorno), ho portato io da casa delle mollette e un filo da campeggio per stendere i vestiti adatto per le mie molette. Inoltre ho dovuto chiedere la sostituzione del phone poiché rilasciava scintille e un set per la pulizia (scopa,paletta e qualcosa per lavare il pavimento), sono dettagli che dovevano gia essere presenti. ( La settimana prima ho soggiorno in una casa a Tokyo ed era fornitissima , c'era anche l'aspira polvere Dyson).

• sandra (9/5): Séjour agréable - L’arrivée autonome, la propreté
• Anna (10/5): - The staff is absolutely fantastic. He is Very friendly and helpful with luggage. Showed up on time to help us with our luggage.
• Saito (8/5): 快適に過ごせました -
• Yamamoto (8/5): - 近くにスーパーなのがあり　良かった コンロが2口あれば直よい
• Patrick (10/5): -
• hazuki (10/5): 心落ち着く旅ができて本当に感謝です！ - 清潔、広々、居心地の良さ、立地、オーナーさんの対応 全部素晴らしくて感謝が沸きました！ ないです。 よく整えられた実家や、兄弟の家にお邪魔するようです。
• Federico Macerola (8/5): Bueno - Facil acceso mediante codigos para obtener la llave. Tiene lavaropas y balcon para colgar ropa. El barrio es bastante oscuro de noche, de todas maneras es seguro. Hay que subir unas escaleras estrechas hasta el departamento, de todas maneras ellos te ofrecen subir maletas. El baño podria estar mejor, se sentian olores fuertes (no se si era algun perfume u olor a baño).
• 怡靜 (8/5): -
• Ciara (9/5): -
• Napalan (10/5): -
• Giuseppe (6/5): Nel complesso completa di tutto - Il servizio di gestione dei bagagli. Struttura non munita di ascensore, e scale molto piccole e molto ripide.
• Gemma (6/5): - Clean, nice facilities, good location. It’s only 1 bedroom rather than 2 as advertised, puzzle floor mats are easy to trip over, very narrow stairs up to floor 2.
• PAULINE (10/5): Absolutely loved this place – highly recommended and would definitely stay again! - Everything was perfect! The room was very clean and comfortable. The design was simple yet cozy. The location was convenient, and the host was friendly and helpful. I really enjoyed my stay here and felt very relaxed. Nothing at all. Everything exceeded my expectations.
• Kati (10/5): - Paikka oli rauhallinen ja helppo löytää. Tilat siistit. Ihanat isot sängyt, kun meitä vain 2 henkilöä, mahtuu 4 henkilöä. Hyvä nukkua. Kiva lisä ylimmän kerroksen parveke. Jotain omituisia ääniä kuului.
• HUI-LING (8/5): - 拼裝地板，拖鞋不好穿，有小蟲。 咖啡好喝。
• Ryhor (9/5): -
• 和也 (4/5): - タオルが用意してあるなら、寝る時の浴衣等パジャマ的な物も用意して欲しかったです。無いので私服で寝る事になりました。
• Felice (10/5): - Come essere a casa propria. Eccezionale Posizione, un po lontana dalla prima metro ma niente di che
• Zhenislava (10/5): A great place to stay in Kyoto - Everything was great - location is close to the main station, Gion and city center. Apartment is in Japanese style, clean, comfortable and with all one would need for a nice stay. I do recommend.
• 渥美 (10/5): -
• CHENYI (10/5): 非常棒👍 - 住宿环境和照片一致，很整洁，设施齐全舒适。 无
• Syoji (9/5): - 行き届いた清潔感 近隣の駐車場がわかりづらかった点
• CHING HSIANG (10/5): 很棒，下次還會來！ - 環境清幽 沒有電梯，行李較重需考慮
• María Paz (9/5): Cómodo, bien ubicado - Muy limpio, cómodo, silencioso Falto más información antes de llegar.
• Aiellomi (10/5): Great space for a family in a quiet part of Kyoto - The location was good close to local train stations and in a quiet but nice part of Kyoto. It was easy to get around and there were lots of nice little restaurants in the area with a great authentic feel! Also having the laundry machine was a big win mid trip. FYI stairs up are steep so would need to be an aware for older people. Plus always asking bottom floor available when looking to book. The floor mats which are used to lessen noise just need a little correction. So could trip on them if not aware. Though doesn’t impact overall score for me.
• Hatanaka (7/5): 快適に過ごせて満足でした。 - 掃除がしっかりされていて快適に過ごすことができました。そして夜遅くから連絡しても素早く返信してくださったので助かりました。 髭剃り用の剃刀がなかったので髭を剃れなかったのが残念でした。それと階段が少し急だったのでスリッパを履いて上がる時に気をつけなければなりませんでした。
• Jassmill (1/5): The attached proof is the rude customer service representative. Booking receipt shows that I’ve selected and full paymen - ‼️The host is terrible rude to me and my family. The booking was cancelled by the host very last minute even an hour before I arrive all the way from Kansai airport. they let us stay in a very cold weather outside the house without allowing us to check in! The reason is when I book, the price charged is for the entire house. I question them how come my message received from the host is only 1 bedroom. The host blame Booking.com for the misleading advertisement posted. The host don’t even give us a chance to check the room condition, they leave us outside and cancelled our booking. Even Luana mentioned its fully refund during the booking terms, until today Booking.com still push this responsibility back to the host side. Both arrows don’t even take responsibility on this and I need to find nearby hotel on the spot at the night time. Until today I don’t receive any response or refund. Please be cautious when you do the booking even their page is high rating. I never have this bad experience before to be honest. Check with the host properly before payment. Terrible attitude, rude Japanese host. Misleading and twist the story and cheating customer. Not a honest landlord
• Maria Isabella (10/5): -
• MARIANO EMILIO (10/5): - Los amenities y la calidez del lugar Nada en particular
• Gandi (10/5): -
• Patrick (6/5): It was ok. - Location The room needs a good cleaning. I did not like the their floor. There was no cleaning tools provided as we stayed for 5 nights.
• シンジョウ (10/5): -
• Rebekah (10/5): - Room had everything- fantastic bedding, kitchen, bathroom, washing machine. Very narrow steep steps to carry suitcase up/down
• Julia (9/5): - Great little place to stay, very clean and comfortable.
• 竹垣栄作 (10/5): -
• yonit (9/5): Nice apartment steep steps to get to 2nd floor - Nice apertment, with all you neen Steep narrow steps to get to 2 floor, location not great
• Ainoa (10/5): - Apartament suficient per a 4 adults, esta ben equipat i net. Esta situat aprop de l'estació de Kyoto i del tren que et porta a Nara, Uji i Inari. Te restaurants de barri al costat que tambe son excel•lents.

• Maja (8/5): Will come back :) Good price for athletic people - The place was located very close to older part of Kyoto ( you can walk, take a bus or subway). I will stay there again for sure. Best place for this price! Stairs were VERY narrow but if you are young and healthy it should not be a problem. The floor was made of some 'puzzles' and it was a bit uncomfortable because it was wobbly.
• taro (10/5): また利用したいです - 使いやすかったです 特になし
• Aranyarat (8/5): - Location , cleanliness , comfort, bathroom is very good Misunderstood about the number of bedrooms .. the property claimed that have 2 bedroom but there’s only 1 bedroom
• 美乃里 (4/5): - キッチン、洗濯機等必要なものは大体揃っていたので助かりました。 床全面にジョイントマットが敷かれていて、衛生面的に隙間に溜まる埃やゴミが気になっりました。一部日差しの良い場所はマット表面がベロベロに剥がれていた。 冷蔵庫、戸棚いろんなところに前泊者の残した飲み物やお菓子、食べ残しが置かれていた。 シーツがニット素材で、全面に細かな毛玉が付いていたが嫌でした… 3階に宿泊したのですが、部屋の入り口とは別にある2階と3階の扉に鍵をかけていましたが、朝方に誰かに何度もノックをされたのが怖かったです。
• Athirah Saharum (10/5): - Love the Japanese tatami concept room and quite spacious for 4 adults. Really surprised the house is clean and near to all the convenience store. Nothing as it was a really good stay.
• Alice (8/5): Très bon logement - Tres bien située Voisin du dessus bruyant, les appartements au Japon ne sont pas tres bien isolés du bruit.
• yafang (9/5): - 房間設施完善、清潔度高民宿周邊安靜🤫 巴士、地鐵方便 取鑰匙的密碼說明不太清楚花很多時間理解
• Regina (9/5): - nice big apartment in good location with fully equipped kitchen required to remove shoes downstairs stairs .very steep narrow steps... difficult with a large suitcase

• beth (10/5): -
• NOBURU (10/5): -
• Tatiana (8/5): - Хорошее расположение, просторный номер Постельное белье не очень комфортное, полотенца выглядели несвежими((
• Silvia (8/5): Ottima soluzione per un soggiorno a Kyoto - La struttura ha i giusti spazi ed è pulita. Il check in è stato facile e comodo. Il pavimento è un po’ rovinato, l’aria condizionata ci mette un po’ a rinfrescare
• Dmitry (8/5): Great location but not ideal for families with young kids. - The property is well maintained and feels fresh and clean. The location is also excellent—just a short walk to a major bus stop that connects you to all the main tourist spots around Kyoto. The bed sheets and linen were of poor quality – we found them very uncomfortable. Also, if you're travelling with young kids, be aware that the building has strict noise restrictions, which can make it a bit stressful trying to keep things quiet at all times.
• De (9/5): Superb - Good location, there is a lot of things you can do in the surroundings if you don't mind the walk. Make sure to have dinner at the Cantonese place nearby. If you know how to use public transport you can go absolutely anywhere without any hustle. The room on the 2nd floor is confortable and the balcony is convenient for laundry. Even though there is no lift the stairs are not that high. They are narrow however but this was not a problem for us. The bathroom is spacious enough for a family of 4. The room on the 3rd floor is smaller, still ok for a family of 4. The room has shampoo conditioner and shower gel and other accessories. The tatami floor was noisy when walking on it and a bit sticky to your feet even though it was clean. The tatami floor did not fit properly and could be renewed. Other then that we had a great stay. The beds are too hard for us.
• Helen (10/5): We had a wonderful stay. - It’s close to one of the temple, Sanjusangen-do Temple and Museum. We were on the 3rd floor. It was fine but the kids were complaining because of the tight space which is expected of Japan.
• Ranginui (10/5): It was amazing, we would definitely return - Luana Sanjusangendo was great. Location was excellent, it was very clean and tidy. The stairs were quite narrow
• El-dib (8/5): Very lovely spot and great location. Very worth it but be weary of cleanliness if you’re picky. - Really loved how spacious it was especially compared to our more central stay in Tokyo. It was a very nice experience! Great area to stroll around at night. Highly recommend the mom and pop convenience store right by!! Unfortunately, we found more “below” surfaces to not be clean (lots of dust under the beds and mold under the chair in the shower).
• Jacqui (8/5): Very good - All the added extras, beds were comfy, kitchen was well equipped, was clean, air con worked great, location was good with a nice walk along the river to the hospo part of town, very quiet. Only downside was the two beds in one room, when sharing with two teenage boys who like to argue!!! And some of the floor mats could do with replacing
• Verse (8/5): Very good -
• Johanna (8/5): A great clean budget accommodation. - This is a budget accomodation, we were arriving late and leaving early so ticked the box for what we needed. I would say one of the cheapest in Kyoto, it is clean and has everything you need, our rooms flooring was a little different than the image in advertising but we can’t complain it was comfortable. The room was a little hot, we stayed in May.
• Chun (9/5): Superb -
• Derek (6/5): A spacious apartment near some of Kyoto’s primary attractions. - The property was clean, new and spacious and well equipped with everything we needed. It was close to a number of the major attractions in Kyoto and fairly close to the transport network. For example, it’s just a 15 minute walk to the Kiyomizu-dera Temple, 30 minutes walk from the Fushimi Inari and just around the corner from Sanjusangendo. The owner was responsive to our questions when we arrived, which was much appreciated. The bed linen wasn’t very comfortable and the apartment wasn’t very warm. It was very cold while we were in Kyoto and the apartment never really warmed up. While everything was new the plumbing system for the three properties was noisy, especially for the apartment on the lowest level. The bathroom was also cold, though there was a fan heater that warmed the room up quickly.
• Anna (10/5): It was worth the money - They have a separate living room Some kitchen utensils you can use too Eg toaster hot jug There was laundry in the washing machine left washed not forgotten to taken out The convenience store is not close you need to walk back to the station which was about 10-15 min
• Francisca (10/5): Exceptional - it was an amazing stay!! location was amazing, we did almost everything by walking. The place was clean and spacious. Loved it!!
• Raindy (10/5): Exceptional - Everything is good. None
• Kira (10/5): Exceptional - Everything was great! Loved the apartment , the place. Would be happy to stay here in the future
• Craig (10/5): Great location with good facilities would stay again. - Great location with excellent facilities. Walking distance to Gion and other attractions in Kyoto.
• Jasmine (8/5): Very good - It was a good location and a nice space. The bedsheet was smelly. They didn't change the bedsheets.
• Corbin (8/5): Very good -
• Chow (10/5): A lovely stay. Very comfortable and convenient. - Very convenient for train and bus links, with some great restaurants nearby and convenience stores. I felt safe walking alone after dark and every comfort had been considered.
• Juliana (10/5): It was very cheap for our group and very comfortable. All the appliances and amenities were good. Very good location. - Everything is just as the pictures: clean, new. Great place to stay
• Belinda (10/5): Comfortable - The beds were very comfortable and clean. It was a nice quiet area and not too far from the centre of Kyoto. It was a nice change of pace compared to the bigger cities. The only issue was perhaps the size of the room for four people. However, this is to be expected in Japan and we had stayed in smaller places. The photos were a little confusing to know what room / floor we stayed in. It would be good if there was a picture of the floor plan that we later found in the room on the wall.
• Vincent_liu_ky (8/5): Very good - Good location, well facilities and nice staff But can be better!!! 1.The stairway is extremely narrow and steep Here are the translations: 2. There is a lot of lint in the washing machine inside the room. It needs to be cleaned before use. 3.There are soap residues left on the toilet seat.
• Jun (8/5): Very good - Location is great, owner is friendly and easy to communicate with. Room is clean. The building is not soundproof, you can hear all the noises from upstairs.
• Panda (8/5): Good value for the price - Comfortable Value for money Kitchen appliances, utensils Beds, pillows and blankets Towels, napkins and toiletries Cheap parking spot very close to the house No vacuum cleaner Dark coloured rooms 10 mins away from bus stop and 20 mins from station
• Xueyan (10/5): Great value for money, lovely staff - Really nice apartment 15 min walk away from Kyoto station. Staff is super nice and cheerful and helped us carry our heavy luggage to the third floor. We only stayed one night but really wish we could have stayed for longer! It comes with an entire kitchen, washing machine and everything is pretty new and clean. At this price in Kyoto, there is nothing to complain about at all and we totally loved our stay. Nothing!
• Ana (9/5): Superb - Clean, complete amenities, spacious
• Bennett (10/5): Exceptional -
• Louise (10/5): Small, cosy, quiet and affordable appartment in Kyoto - This may have been the best price/quality hotel I’ve ever booked using booking. I had a whole appartment all to myself: two beds, a tv, bathroom with japanese bath, kitchen and balcony. All of this for only €14. It was just what I needed after weeks of staying in hostels (that were mostly more expensive). Thank you very much!! Nothing. It was more than perfect.
• William (10/5): Happy to have found this gem of an accomodation - Our family of 3 (2 adults and 1 child) stayed here for 4 nights and absolutely loved it. The 3rd floor apartment was very comfortable. It was very well equipped and by Japanese standards it was spacious, too. The bathroom even had a tub. Everything was labeled well with English instructions and easy to use. The beds and pillows were very comfortable. Everything was very clean. In my opinion, for what we paid, it was excellent value. Self check-in and check-out was convenient. Internet and heating worked well (we stayed in winter). Great water pressure. We would happily stay here again! For the foodies: I found a conveyor sushi restaurant 5 minutes walk away, named Maru, and ate there every day. Fresh and well priced. Highly recommended. Everything was positive. Zero complaints.
• Robert (10/5): Exceptional -
• Francelis (10/5): Very cozy, traditional and convenient. - This house really makes the Kyoto experience whole. First of all, the location is very convenient, 15min walk to Kyoto Station, multiple restaurants and convenience stores around, really close to the river so you can enjoy a couple drinks and a fun time with friends or family. I came here from Tokyo, and it was very soothing and relaxing. The unit is very spacious, with traditional tatami floor even. Has all the listed commodities like laundry machine, 2 comfortable beds, and even 2 air conditioners. Without this spot, my trip would have changed drastically, and if I come back to Kyoto, would 100% book this place again. I loved everything.
• Benedict (9/5): Overall it is good option staying at Kyoto. I would book the first floor instead of 3f specially coming with my family - Amenities Location and the flight of stairs
• Jan (10/5): Has all you need - The apartments are small but they contain absolutely everything a traveler would need. Down to the nail clipper, Netflix channel and a little balcony to dry your clothes. The bathroom is small by western standards but it had everything one needs and is actually quite comfortable. We enjoyed our stay in the small apartment on the 3rd floor. It is advertised for 4 people, we were 2. If you are 4 and booking this apartment think that you must really like each other however to make it work. The apartment is super close to an amazing temple we're we spent a lot of time. Also the metro line is not far. If we come back to Kyoto, we would book this apartment again
• Johnston (10/5): Perfect apartment stay in Kyoto. - The house is located in a convenient area, with access to kiyomizu, national museum, fushimi inari, etc. The bed and room situation was even more comfortable than pictured. The apartment was spacious, very clean and organized. Two air conditioners made for a very cool stay in the heat of summer. The host went above and beyond to sort out issues and made our stay very worthwhile. I would definitely recommend staying here, it is much better than a busy overused hotel chain.
• Raymond (10/5): Awesome stay - I cannot be more thankful for this booking. Location was superb, beds were really comfortable. Aircon kept us cold. Shower/bath was awesome. Very responsive manager. Easy check-in and check-out with keybox.
• Neitzel (9/5): Superb -
• Stan (10/5): Exceptional - It was a full apartment including everything. The shower was great, the beds were great, living room with netflix and a fully equiped kitchen. There was also airco and a washing machine which was incredible. Checking in was a little difficult but that was literally the only thing I could complain about.
