I do not recommend for a first time in Seoul.
Hence the staff was really nice, the hotel itself is far from the main attractions if you are a first timer in Seoul. Also the room had a terrible smell, windows were not cleaned for the past few years, we could hear the room next door and the restaurant just above our room. There was an automatic light in the room entrance which was really annoying, the AC dropped on the bed and the bed was very hard, not comfortable. I think the price is overrated compared to the experience.
