Koichi's place is very nice and spacious. We had a comfortable and relaxing stay after all the tours we did around Tokyo. We had plenty of luggage - the 2-3 minutes walk from station is fine with us. Had a little problem locating the apartment as some houses in the guide map have changed but thanks for Koichi's responsiveness we were able to find the place. Nearest station is 2 stops away from Shinjuku station where we took the Airport Express limousine/bus going to the airport. Thank you!
