Koichi's place is big, homely, comfortable and clean. Even with 3 of us, we could still moved around the room easily. After each day's outing, it always felt great coming back to the house to rest. Location wise is great as it is within walking distance from Shinjuku Station. Koichi was a great host, he came to fetch us from the station upon our arrival and drove us around to familarise us with Shinjuku. As we were 3 ladies with big heavy luggages, he didn't hesitate to help carried our luggages up to 2 flight of stairs to the house. He even left us his contact number so that we could contact him for help to get direction to places, advises on trains, recommendation of food and restaurants, which he always responded timely. Thank you Koichi!
