Mitsuko is a wonderful and interesting host, always willingly to help. She also owns a cool looking dog. Apartment is a typical japanese sized room, modestly furnished. Close proximity to Shinjuku station, 2 stops away. Convenient to travel around. Even though the room is small, spent most of the time out so it didnt really bothered me. Quite a quiet neigbourhood, they do have some shops that operates at night. So if you're hungry, you can easily grab something to eat.
