10/10 location. Checkin and communication with Yoshihito is great and smooth.
For more than 2 people it is quite cramped, but that is as expected from the photos and description.
One thing that is unpleasant is an emergency exit sign that has a very bright light. Since its all just one room, the sign lights up the entire room at night, making it hard to sleep. If you are light sensitive, be sure to bring a sleeping mask.
Overall would definitely recommend for a budget stay in an outstanding location
