Good points : good location for traveling by bus in Jeju, quite okay rooms, good and large bathroom, it was clean.
Negative : the bed was hard, it's certainly not for those who wants a comfortable bed. I had a windows in my room but it's not for the view as it was only facing the building 2 meters away. They didn't provide a "do not disturb" sign in the room, so the room is cleaned everyday and they change the towels even when you don't need it/I wouldn't have asked for it... (That's not cost saving/ecological).
But for the rest it's a nice simple hotel room, it does the job for a reasonable price.
