Jiao is a wonderful host and responds ultra quick. The apartment is clean and has just about everything you need for a comfortable stay. Accessibility is a huge plus, since it is just across the street from a huge shopping mall (Tokyo Solamachi), a 7-11 downstairs and the Oshiage train station few hundred meters away. The apartment is reachable 9 stations (~1 hour) using the Skyaccess train from Narita airport. I would highly recommend it!!
