It’s a small apartment on the fifth floor of a walk up building. Not great if you have big bags or small children. Think Brooklyn apartment.
But everything else is wonderful. Futon beds on tatami mat floor. And the flat is in a terrific location between Ebisu and Shibuya stations. Loads of great food shops and restaurants in way walking distance. JR rail pass travelers can get all over the city or country from here.
And the hosts are outstanding. They lived for a time in California - their English is perfect. They were extremely gracious with our family, and entirely professional in setting up the reservation. (They have the new license to legally operate an Airbnb).
