I had a private room. The room was small but perfectly furnished with everything you need including a kitchen, a comfortable bathroom and free Wifi. Everything was new and perfectly clean.
The staff is helpful and extremly nice. The location of the place is great as the nearest Metro station is Sinchon and goes almost everywhere in Séoul directly. The disctrict is animated, with bars, stores and restaurants all over but my room was really quiet.
If you caannot afford going to expensive hotels I warmly recomand this place as you will find everything you need for enjoying Séoul at its best.
