Kentaro's apartment was a great place to stay for our family of 4 - two big rooms, separate bathroom/toilet, living area, and very clean.
We found the apartment comfortably warm during a cold January week, and the rooms stayed warm with the heaters off while we were out during the day. Family Mart and Lawson close by, and 5-10 min walk to restaurants near Kappabashi/Senso-Ji, as well as some nice restaurants in the street. Kentaro provided info on local shops and restaurants, so this was handy after a long day when we wanted to make quick decisions!
Easy walking distance to Ueno and Iriya stations - which are easy/ direct to Shibuya/ Shinjuku, Ginza etc, as well as to DisneySea (under an hour).
A great apartment,with lots of room, at a very reasonable price - highly recommended!
