It's a 5-min walk( or less) to the nearest train station, Shin-Okubo. It is easy to locate and has multiple supermarkets nearby. It is suitable for max 4 people, though I booked for 5. Waiting for the toilet is a hassle and space is an issue as the 5th person has to sleep on a thin futon. It was too cold. Good stay, 4/5.
