We loved our week-long stay at Haifang's place near Higashi-Nakano station! Never having traveled to Japan other than passing through the airport (though having traveled many times all over the world) I was a little nervous to see the exact location, ease of travel from there, noise levels, etc. Everything was beyond our expectations.
Haifang gave excellent written instructions on everything, with photos, to the point that we never needed to go over anything in person. She anticipated everything an overseas traveler might need to know.
we absolutely loved the quiet, very non-touristy neighborhood, which has plenty of shops and restaurants within walking distance.
Haifang was extremely responsive to messages via Airbnb all through the process; usually within a minute or two!
we will very much hope to come back to Tokyo, and if we do we will look no further than this place.
