Nice little hotel in a nice place. Many bars and restaurants nearby. A few blocks from the subway. The room is comfortable, with floor heating, air conditioner (although the controller for it was not there), hair dryer and etc. Amenities like toothbrush, toothpaste, soap and shampoo provided. Breakfast is simple, but ok. The staff is nice, speak good english and most of time very helpful.
The only cons are the shower (in the middle of the bathroom without curtain or glass, what makes the entire bathroom completely wet after you use - something quite normal in Korea but still very weird and uncomfortable for me) and the check in/check out times (15h/11h).
