We had a wonderful stay in Koichi's apartment. Koichi is an excellent host and went out of his way to accommodate any needs we had. We are greatly appreciative.
Kochi's apartment is in a great location, only a short walking distance from Shinjuku railway station. There are restaurants and supermarkets very close to the apartment.
The apartment housed our adult family of 4 very nicely and we'll stay there again when we're next in Tokyo.
We'd highly recommend Koichi's apartment!
