This apartment is exactly what you see in the photos and description. :) It's a very clean and comfortable space (the bed is very good), small, as japanese apartments usually are, but a good size for one or two people. Meijie is a great host, easy to communicate with and helpful.
The location of the listing is also quite practical, close to Yoyogi and Shinjuku stations, and to some nice spots in Tokyo, and also with a lot of nice restaurantes in the neighbourhood.
The portable wi-fi is a must for everyone who's visiting Japan, since google maps is essential for walking around. :)
