Masami was available by message if needed, we had few questions and she nicely helped us. Her accomodation is very convienient, we spent 1 week at four and we felt like home. The kitchen and bathroom facilities are great. We didn't cook, just prepared our breakfast but we could have. There are plenty of closet and place to put our stuff, at least for 4 people : it would have been small for 6 or more. The accomodation is nicely decorated, calm and clean. The distric is convienient to have dinner outside, but also very close to Shinjuku and Shibuya to go out by night. Very easy to reach by transport, the JR line is not too far (Shinjuku)
