The apartment was spotlessly clean and had ample space for my family of 4. There is also sufficient space for 4 large luggage bags (unopened). Apartment is about 5 mins walk from shinjuku sanchome station or about 15 mins from the main shinjuku station. The apartment is situated in a quiet neighborhood with a convenience store a couple of mins walk away. Koichi san was really helpful, offering to pick us up from the shinjuku station the day we arrived and also sending us there the day we left, solving the problem of lugging the luggage from the station. My kids also especially enjoyed his complimentary ice cream mochi. All in an excellent host and apartment. We will not have any reservations staying here again when we come back to Tokyo.
