Rintaro-san's house is very cool and cozy. My wife and I were travelling for vacation, and we decided to stay while we explored Tokyo. The location is nice, a bit outside of the city proper, it's nice and quiet. There are plenty of grocery stores and drugstores right outside. The house is only a few steps from the subway stop (which lets you connect and get all over Tokyo). The room itself is small, but very cool and cozy. My only complaint is that there really wasn't a place to put our clothes. There isn't much space for anything really. But, we're not picky, so we didn't mind keeping things in our luggage. The bathroom and the shower and very cozy and nice. The little kitchen was the nicest we had in our entire trip. Very nice. We really liked the style and were very comfy. I would be glad to stay again.
