We had the pleasure to stay at Kanae’s place for a few nights. It is very big for Tokyo, and a pretty easy walk to the station as well. It is located near Shin-koiwa station, which is on the convenient Chuo-Sobu line that goes straight into downtown Tokyo.
Responses were always very fast, and Kanae was very helpful if we ever needed anything. Highly recommend staying here if you find yourself in Tokyo!
