Great communication! It is such a nice and warm house. Everything is clean and tidy. It has three room in total. Every room was with heater so we are warm even in winter. Both upstairs and downstairs have toilet. There is one separate shower room on downstairs with 2 basin. We have 7ppl and we are happy for that. It was so comfortable. Ritsuko let us check in early and this bring us a lot of convenient. Ritsuko pick us up at the station and bring us to the house directly. It’s a 5-7minutes walk to Yotsuya sanchome station. There are lots of shops and restaurant nearby. When you come out from the residence area, you can get to family mart by just crossing the road. Overall, we had a great time in Tokyo. Highly recommend to stay in Ritsuko’s place!
