Fabulous location! Min and Haru are fantastic hosts. They speak fabulous English, are very easy to approach and talk with, and have been very hospitable. The building is located closest to the Tokyo Metro station Higashi-Shinjuku, and is also within a short walking distance to the Yamanote line Shin-Ōkubo Station. Access to both of these lines means that getting pretty much anywhere in the city was a piece of cake. The room was clean and spacious. Highly recommend!
