This place is definite winner in a bang for buck category. Location is a bit seedy with adult establishments around it (if you are sensitive to this sort of things) but it also really conveniently located to everything, and Shibuya station is one of the best starting places for exploring Tokyo. Photos are pretty accurate, but the actual place looks a bit more "tired".
The place if officially registered lodging.
Owner/Manager responds really promptly and is proactive in communication. Owner requires to submit a photocopy of your ID, even if you are a Japanese resident (Minpaku law states that Japanese residents only need to submit name, address and contact info).
