Overall great experience. The staff were patience with my limited Japanese and knew some English. I really like that you can request umbrellas, nail clippers, toothbrushes, etc.
My only dislike was that the AC was not activated for the building yet as it was only Spring. This would be okay if I could leave the window open, but the window has no screen so bugs could easily get in.
Also the bathroom had a constant smell of sewage, as if there were some sort of leak. Our friends in the room beside us had the same complaint.
