It was such a warm and pleasant experience. Koichi San was being very friendly and helpful, with his warm welcome we didn't encounter any issue at all. Mobile wifi was such a big plus, it helped us to cruise in the city with no problem at all. The house itself was very clean and home-like atmosphere completed with amenities, located in the heart of shinjuku but very quiet, with convenience stores, coffee, restaurants and 2 metro stations around all in a short walk. Very close to JR shinjuku station and major department stores. This property with such an human touch is highly recommended by us, will stay there again.
