Clean; quiet, nice materials.
The AC unit is weak, and they do not pre-cool the room, meaning that during the summer it’s uncomfortably hot when you arrive.
To power the AC unit, you have to put your key inside. This means if you leave with your key for the day, it will be hot when you return since it’s not actively cooling.
Friendly staff, clean, big by Kyoto standards. Would stay again. Ask for a second key, and just keep it in to run the air condition.
