- Попов (8/5): -
- Gamze (1/5): Nie wieder werde ich dort hin fahren - Personal waren Freundlich Thermewasser war kalt , es gab Probleme mit Warmwasser , war nicht zufrieden.
- Am7nz (10/5): -
- yasın (1/5): receptıon ilgisizdi - bellboy arkadaş ilgiliydi ilgi alaka dıe birşey yoktu havuzun yerini gösteren yok sormamiza ragmen receptıona havuz nereden gidilir die soruyoruz adam akıllı bır cevap alamıyoruz sabah siftinde çalişan arkadaşlardan
- Pinar (7/5): - Das Zimmer war sehr bequem und große Mangel an Hygiene und das persona war nicht so freundlich wie es sein sollte
- Mhd aman (7/5): مكان جيد بادارة قبيحة وسيئة جداً - الماء الحار والموقع لان معي سيارة تعامل الموظفين سئ جدا جدا جدا ويضحكون على الزبائن بسخرية وغير مستوعبين انهم واجهة لبلدهم.. موظف الاستقبال في الفترة المسائية كان احمقاً وحاول استفزازي بدون داعي سوى لاني اتكلم الانجليزية!!! وموظفة الساونا المحجبة ضحكت على سياح كبار في السن وسخرت منهم
البخار لم يكن يعمل
الحمام كان فيه تسريب
موظفة الافطار مع العمال كانهم متفاجئون بالزوار
الاطباق في الافطار فارغة ويتأخر تعبأتها بقصد!!
حتى موظف الالامن الخارجي جاءني بعد عشر دقائق من وقوفي واجبرني على تغيير مكان السيارة تحت المطر علما بان الموقف صحيح🤪
باختصار الموظفون اعطيهم سالب خمسين🤬
- Suzan (8/5): Prima - Hygiëne is prima in de kamers. Ontbijt is goed. Warme welkom van personeel ontbreekt.
- Adalet (10/5): -
- terry (6/5): -
- Tatiana (7/5): По цене было дешево но я больше не вернусь . Девушка на ресепшен была очень любезной и отзывчивой ей я бы поставила 10 и - Цена была самой низкой В отеле требуется ремонт, в спа плохая проводка, от электрического счетчика исходит звук. Провода огаленные на светильниках рядом с водой , плохая вытежка в спа вода капает с потолка
- Cesar (10/5): -
- Batuhan (6/5): - 7.katta kaldık, 30-40 sn aralıkla asansörüm gümbür gümbür vurma sesini gece boyu dinledik. Banyoda su neredeyse akmıyor seviyede az geliyor. Ortak kullanılan havuzun sisteminin bozuk olduğu söylendi, buz gibi suya girerek Termal tatil keyfi yaptık. Tek iyi nokta garsonların tavırları ve yemeklerin kalitesi diyebilirim.
- Donald (6/5): - Not much the pool and spa ect was nice but regretfully because it was out of season no restrauant was open and it's not in a location where you could walk to a restaurant Poor location and no restaurant open at the hotel which on booking.com indicated otherwise

- Anar (10/5): -
- Verified traveler (8/5): - Spa alanı ve masaj hizmeti güzel, odalar konforlu ve büyük, temiz. Tek sorun Aquaparklı havuz temiz değildi, rahatsız olduk yine havuz çevresi yerler pisti. Bu nedenle tekrar gelmeyi düşünmüyorum. Termal ve dışarı havuz içi ve çevresi sürekli temiz tutulmalı.
- Ahmet (1/5): Finger weg, kein 5 Sterne Hotel! - Nichts Das Hotel hat keine 5 Sterne verdient. Nicht ein mal 1 Stern. Die Zimmer waren sehr dreckig. Es gab kein Warmwasser. Die Lampen haben geflimmert. Wir hatten 2 Zimmer gebucht, und beide waren im selben Zustand. In einem Zimmer war das Bett schon benutzt und nicht sauber gemacht. Erst nach drei maligem Bitten wurde das Bett neu bezogen. Die Klimaanlagen funktionierten nicht. Das Möbilar fiel schon auseinander. Haben es für 3 Nächte gebucht, sind dann nach einer Nacht in ein anderes Hotel gegangen. Wir hätten es nicht noch eine weitere Nacht in den stinkenden Zimmern ausgehalten. Die Zimmertüren gingen nicht zum Abschliessen. Das Personal war sehr unfreundlich. Man hat uns beim Einchecken nicht einmal sagen können wann und wo es Frühstück gibt. Das ganze Gebäude sieht aus, als ob es 100 Jahre alt ist und nie gepflegt wurde. Nie mehr wieder dieses Hotel!!!!
- Verified traveler (10/5): Güzel - 1 gece için gelip doyamayıp 2.geceye de kaldık. Çocuklarım çok memnun
- Hassan (8/5): Good value - The overall ambiance was good with professional staff . Hammam and hot pool were excellent . The furniture is very old and not comfy. Communication was hard as most of staff speak only Turkish
- Eva (7/5): - Nice outdoor swimming pool and very pleasant spa hot pool, polite receptionists Reconstruction in progress on our floor, dirty and noisy corridors, breakfast without juice
- عبدالمجيد (9/5): -
- Andra (8/5): A good price-quality balance - The staff is very nice and helpful.
The rooms are big and fully equipped.
The hotel has thermal baths, pool and spa.
The breakfast partially changes every day.
The restaurant serves breakfast, lunch and dinner.
There is no traffic noise since the hotel is far from the street. The hotel is visible to have been a 5* one, but needs an upgrade.
The plumbing in the bathroom I used needed to be changed, the bath robes no longer had the cord attached etc.
During one of the mornings, the cheese rolls at breakfast seemed a bit old.
- عبدالمجيد (10/5): - مكان وتعامل وطعام وخدمة

- Nawaf (6/5): -
- Angelina (6/5): Отель тянет на 3-4 звезды - Бассейны не сильно чистые, но нормально, пойдет, в день нашего заезда не работал бассейн и аквапарк на улице , починили только на следующий день и то работало 2 горки только. Нам об этом за ранее не сообщили , сказали только после оплаты, что очень нас расстроило, возможно, если бы сообщили раньше, то мы бы сменили отель. Отель явно не тянет на 5 звезд, я бы оценила на 3-4 звезды. Напитки в ресторане все платные, кроме чая кофе и воды.
- Adrian (5/5): Passable -
- Wesam (4/5): Poor service, no air conditioning in 39c temp - Poor check in. Wanted to check in and go to a business meeting. Couldn’t get to one of the rooms as the key wasn’t working. Went down four times to reception and wasted 45 minutes and nearly missed my meeting. Hotel is not very clean. Air conditioning doesn’t work and when you ask for it to be fixed they lie to you and say we will get it to work which never happens. I travel every 6 weeks and I visited more than 120 hotels,”. This is the worst hotel I ever stayed in and I cannot believe it’s rated with five stars. I will never go back there ever again.
- Jonathan (10/5): Exceptional -
- Tursun (10/5): Exceptional -
- Dmitry (8/5): Very good - Great thermal pool inside Absence of a bar in hotel
- Rami (7/5): Good -
- Abdulrahman (10/5): Exceptional - Perfect hotel .. you can stay your day and night inside it and you don't need to go out
- Antonio (1/5): Bad - Beds are nice and clean. The hotel had no water supply for half morning.
I woke up to find NO running water in the toilet at all, for many hours.
And it is a Spa hotel...
They said there was some sudden main pipe damage or whatever, but they just didn't even apologize.
Its like it never happened, but I had to leave without taking a shower, or flushing the toilet.
- Vady (10/5): I found the comfort I was looking for, and everything in one place. - The swimming pool and water games, and the hotel's location close to nature. I also liked the treatment of the reception staff, Arslan and Eda. Everything is perfect 👍🏻
AC sometimes not working as well as the weather out side too hot
- Laurentiu (10/5): The best! - All All
- Cenk (8/5): Nice spa hotel - They have nice spa concept Not ready yet - when i was there open air pool was not on function
- Amel (10/5): Exceptional -
- Endercan (8/5): - Yatak örtüsü lekeli idi.Personel güleryüzlü ve yardımsever
- Fatih (6/5): - Termal deneyimi yaşadım hamam ve sauna güzeldi.
- Toader (5/5): Passable - Price was good. Air conditioner wasn't working. It wasn't hot, but wasn't comfortable either.
Could be cleaner and better maintained.
Not a 5 star hotel. Not never an 4 star hotel
No wifi in the room.
- Cengizhan (4/5): Bu sefer hayal kirikligi yasadik - İlk gittigimiz de hersey mukemmel di ama ikinci konaklamamizda sauna buz gibiydi karisik termal havuz bosalmis kapali digeri soguk yani hayal kirikligiydi

helpful and welcoming staf
- Seyma (6/5): - Kızımla haftosaonu tatili için gittim. Genel olarak idare ederdi diyebilirm. Oda temizliği çok iyi, ona lafım yok. Ancak restoran yemek kalitesine göre çok pahalı. Termal havuz asla sıcak değildi sadece bir kapalı havuzla aynı sıcaklıkta idi. Arabamı şarj etmek istedim, dışarıda 4 tane şarj istasyonu var ancak sadece üyelik kartı ile çalışıyor ve nasıl kullanılabileceğini bilen yok. Güvenlik resepsiyona, resepsiyon güvenliğe yönlendirdi. En son bilen arkadaşımız burda değil dediler, telefonla ulaşamaz mıyız dediğimde ise işten çıktı cevabını aldım. Valizimi taşırken yanımda küçük çocuk olmasına rağmen kimse yardımcı olmadı. Çocuk oyun alanı aşırı soğuk ve rutubetliydi, doğru düzgün oyuncak yoktu. En azından ısıtamaz mıyız diye sordum, teknik ile görüşüp mümkün olup olmadığını soracaklarını söylediler ama sonuç olarak ısınmadı ve haber veren de olmadı. Biz tatilimizi sorunsuz tamamladık mı tamamladık. Büyük b eklenti ile gtimezseniz mutsuz olmadan dönebilirsiniz.
- Soner (10/5): - oldukça konforlu bir otel personel ilgili ve yardımcı
- DUYGU (10/5): Güzeldi - Oda çok temizdi. Çalışanlar ilgili. Havuzda güzeldi. İstanbul’dan gittik. Havuzda temizdi memnun kaldık. İnterneti de iyi. Odanın ısı ayarınıda istediğimiz gibi ayarlayabildik. Otel çevresi sakin ve huzurlu. Başiskeleye çok yakın sahile. Sahile dolaşmaya ve kahve içmeye de gidin mutlaka.
- Fatih (10/5): - Resepsiyon ilgilisi beyfendi gayet ılımlı şekilde 1+1 oda verdı standart oda yaklasımında gerçekten rahattı termal havuz kullanma ımkanı mevcut benım en begendıgım kısım otel ve oda sessiz sakin kafa yormuyor ayı zamanda kahvaltısı cok ıyı ve restaurantı gayet güzel. tekrar tercih edecegim...
- Cengizhan (8/5): - Sigara icmeye en azindna balkonu olsa iyi olurdu ama genel oalrak her sey iyiydi
- Simge Cemre (2/5): - Otel ve termal harika. Ancak otelden çıkacağımız sabah termale girmek istediğimizde bone olmadan giremeyeceğimizi tanesi 150 tl olan boneleri alıp o şekilde girebileceğimizi söylediler. bu otele 3. Gidişimiz ve kimse bize daha önce Bone takmamızın zorunlu olduğunu söylemedi. Bu oteli tekrar tercih etmeyi düşünmüyorum, daha önceden söylenseydi bonemi alıp girerdim ama normalde olmayan bir kuralı sırf bone satmak için zorunlu hale getirmeleri çok can sıkıcı bir hareketti. Tatilimizin son anını gerginlikle dolu geçirdik.
- Yasemin (10/5): Izmitteki duragimiz - Otel temiz odalari genis konforlu kahvaltisi gayet guzel cevresi guzel merkezi yerlere yakin calisanlari guler yuzlu 2 kez konakladik.
Ilk sefer kalabalik degildi ama ikinci sefer otel cok kalabalikti insanlar sebebiyle biraz rahatsiz olduk sadece tavsiye ederim.

- sevgiye (10/5): - Kötü yorumları görmemize rağmen tercih ettik. Hiçte pisman olmadık. Temizligi, ilgileri, kahvaltısı gayet güzeldi.
- Yousef (9/5): Beautiful Stay in Izmit - The hotel was very clean, and the staff were so polite and helpful...rooms are comfortable and spacious, breakfast is good but can be of more selections. Slides of the pool were exciting and the kids enjoyed sliding on it, the sauna & steam rooms were good also. The location is a little isolated and there are no services in the neighbourhood. You need to have a car as no restaurants or supermarkets are adjacent within walking distance.

- Aykut Necati (8/5): Hotel ok - Hotel eigentlich gut doch die Qualität an Speisen ist nicht besonders für einen 5 Sterne Hotel. Renovierungsbedürftig. Spa nicht ganz sauber Decke klein Teil abgestürzt. Massage aber Top. Steckt viel Potenzial die man noch ausschöpfen könnte. Rezeption Personal sehr nett und hilft gern.
