Be very careful which subway exit you take, and it’s the gray metal gate right outside the Toei Nakai North exit. Location was VERY difficult to find, and Google Maps gives directions that make no sense, both coming & going. Your best bet leaving is to catch a stream of people exiting the station and follow the herd around hour. Beware the top bunk’s ladder — request lower bunk if any mobility issues. Very comfortable bed, hostel is just right for the price. Highly responsive & courteous staff.
