We had a great time at Ken and Mayu’s! The studio is full if nice touches and a very comfortable place to stay. It can be a little tight for a family of 3 with luggage at times but I think that would be the case in most places in Tokyo. The location is great, in a very nice residential area and also pretty close to train station. Lots of nice restaurants around. The only downside would be that the studio is underneath the host’s residence so you can hear them walking around quite a bit, but we overall had a great stay and would definitely go back.
