Great location(can't go wrong with Togoshi-Ginza area), great communication (Yoh responded quickly when we had a questions), great amenities. We enjoyed our stay very much and would definitely come back!
Water pressure with shower was perfect and the laundry machine in the unit was very helpful while we were there for a week. Bed was super comfy, too. It's a very cozy and real functional place!
Just be aware if you are tall that the bathroom is very tiny and the kitchen light is hung very low. Think as this is some unique tiny house experience and note that the size is normal in Japan, although my husband is very tall so he hit his head with the light a couple of times a day.
Also if you stay for a week or longer, you notice that there's no closet or drawer. We just kept our clothes in the suitcase during our stay. It's understandable and not a big deal at all since the space is limited but would be nice to have one.
