Courtyard by Marriott Sejong

Location near the lake and cleanliness

None

the ambience was great

Very nice room. Big incredibly comfy bed, good shower with a lot of space, and a well kitted bathroom. Room is nicely lit with good options to adjust the lighting, TV not world-beating but high-res and a good size, has youtube and netflix - but you need your own account. The hotel is very clean and kept to an impressive standard. There is a cafe, bar/lounge and restaurant within the hotel. An extensive room service menu of korean and western style food is avaliable for in room dining too. I only dined in my room but it was easy, the staff were polite, and the food was real tasty. To top things off - at least from my room on the 15th floor - the view from the whole-wall window was tremendous. I had city view but the lake view was even better!

Although very pleasant it is not the cheapest, this also applies to the food which again was very nice but considering how inexpensive it generally is to eat out in south korea, wasn't exceptional value. Far from overpriced though. The laundry service is per-item and quite expensive so be aware if you are planning to use that.
