Ritsuko and John's home was an excellent base camp for our family of four. Two teens slept easily in the second sleeping room.
If you are from the US it may seem cramped, but my large corporation executive friend who lives close by said it is a very roomy home by Tokyo standards. We loved it.
Very functional kitchen. Washing machine, small room for hanging items and storing bags, good lighting.
Ritsuko was very flexible with check in and check out hours.
You are a five minute walk from a metro line and a 15 minute walk to a mainline JR train. Dozens of restaurants are a 5 minute stroll away. 1.2 mile scenic walk to Shinjuku station. In fact you are a short walk to just about anything you could possibly need, both Japanese and western.
We really enjoyed the home and location. It's in a very active area, yet it is down a quiet alley so is completely silent for sleeping at night.
Thank you Ritsuko and John!
