I booked this because of the “adults only” element (thinking it would be nice and quiet) and the location (near shinjuku) - without being aware of what a Japanese love hotel was. The amenities in the room (sauna, karaoke) were fun but I would not stay here for an extended period of time. The longer we stayed, we realized the quirky/mismatched decor was mostly there to distract from stains, and although the staff were prompt and kind, it still never felt completely clean. Safety was also a concern as the lock was key based, we were always asked to return the key before leaving, and there was no second lock to prevent anyone from getting in while we were in the room.
