I am an American and stand 6'5". The apartment is small but very functional with everything you need for a short or long stay. The host was very responsive to all of my questions. We had a slight problem finding the home and had to backtrack to the station to get our bearings. The supermarket is an immediate left upon leaving the train station and the colors of the sign are no longer a dominate red but grey in color with red lettering. We picked this location primarily to visit the Ghibli Museum and it is only one stop away. The museum is located in a lovely park that whisks you away from the hustle and bustle of Tokyo. There are quite a few small shops, cafes, hair salons etc adjacent to the apartment. The supermarket is extensive with anything you would want from snacks to cooked food to items needed for a home cooked meal.
I did notice a slight musty odor but my wife did not. If returning to this area I would have no issues with staying here again.
