The Bad:
Personal preference, but the mattress was super firm, almost hard. I didn't ask if there was a mattress topper option available, being that I didn't speak Japanese very well.
The "accessibility" option for disabled guests was only a shower chair that they brought up to the room and placed in the tub. I am a little more able-bodied than most wheelchair users, but still had difficulty getting into the tub (height was an issue). The door to the toilet would not accommodate my walker, too narrow, so I had to collapse my walker to get it into the toilet area.
The bidet was dripping the whole time, but it did work, so there's that.
The bathroom had a slight smell, kind of a musty smell. The "couch" we put the two chairs together to make a couch, was stained, and very hard to sit on for very long.
The Good:
The staff was very helpful, and welcoming.
The location was VERY convenient.
The washer/dryer all in one machine with detergent, the mini fridge, cooktop, dishes, made it worth the stay for the use of these things!
