The Nakano apartment by Shin and Sho is wonderful! It's been a great experience as the apartment is nice and cozy, very warm and extremely clean.
Shin and Sho have been extremely thoughtful, giving information to reach the apartment from higashi-nakano station. The walk to the apartment is very nice, a good glimpse into the neighbourhood of every day Tokyo. Generally we were really happy with the whole experience.
The hosts were also very helpful; answered our every trivial question with lots of information and were all useful. It help saved a lot of time as we only had three days in Tokyo. Thank you very much! :D we'd definitely come back in future :)
