The rooms are on the small side and well appointed. A highlight is the Toto Washlet toilet/bidet. However, I wanted to like the Granbell but experienced multiple issues during my week-long stay. First, the rooftop bar food is subpar but expensive, and the service is only so-so. There were also multiple late night (very early morning; 3 am) false fire alarms, which was very disturbing. On arrival, my room had no hot water, and then on the last night of my stay my room (only) lost all power. The cleaning staff also neglected to provide any towels when refreshing my room.
