First of all this place is very affordable but, the rooms are super tiny. Feels more like a dorm, the bed is very comfortable, there is a small fridge and a nice bathroom and tub.
The facilities are really great, very spacious, working areas, the gymnasium is huge and very well equipped with weights, treadmills, and Pilates equipment. You get a daily breakfast, consisting a soup of the day, salad, bread, and a beverage. There's laundry and shared kitchen available.
The location is prime close to restaurants and bars, and only a 10 minute walk to Hongik University subway station
