Think of Sotoshi’s place as a bit better than a hostel. Everything you need, quiet, private rooms, and clean.
Body soap offered is unlabeled and foaming, like hand soap, so I’d suggest you bring your own. No Shampoo or Conditioner. Bed is very firm, which I like, but my wife does not, so something to keep in mind. Also, our hair dryer outlet was not working properly. Room #21.
Overall, a good stay and would go again with these items in mind.
