As any other guest mentioned, the location is very convenient, easy access to convince stores, underground and bus stop. Y is very friendly and always tries to help if there is any problem. I would suggest the house is only suitable for small group as it may be difficult to open the suitcases. Hard to tell from the pictures, but the first floor is only bedroom and bathroom, the living floor is on the second. And there is no much of space around the washing sink so it might be difficult to do make up if this is a issue for you. Generally, house areas are not particularly big in Japan. Other than that, I would recommend the place if you want to explore the Sinjiuku area.
