Stayed at Hiroya's place for almost a month and I can only recommend it!
Room 201 is small but it is a private room with a desk, air conditioner, a window and keys, so you basically have everything you need! I stayed at Hiroya's place for almost a month and I didn't have any problems at all. Also, Jujo is a very nice place with a good and fast connection to all the main stations in Tokyo (Ikebukuro, Shinjuku, Shibuya).
