The room is not too big but just nice and clean. We arrived on the day whereby they had maintenance going on, we couldn't use the waterline heater. However, the front desk is very polite and willing to help.
It would be great if the hotel could add their exact location in Naver Map as the main entrance is located inside an alley which the map's couldn't direct you to. We were lucky to have the locals reached out to us and show us the entrance.
