Ritsuko's place was everything we were looking for - enough space for 6 people, great location, clean and comfortable. Ritsuko and John were very accommodating with flexible check-in and check-out times, tried to help us make a reservation at a restaurant ahead of our trip and were very responsive if we had any questions before our trip and during. They also have a lot of Tokyo guide books and suggestions to do while you are in town. Bathrooms are a bit small but all bathrooms are small in Japan! It got pretty cold downstairs and hot upstairs, but Ritsuko has a small space heater for the downstairs that helped. Overall, a great place and would recommend to anyone staying in Tokyo!
