We have stayed here during our visit in Tokyo. Room is not big but it's fully functional, very clean and ready to use for visitor. location is great as it is near to both JR (Shimbashi station) and subway station. Documentation/instructions such check in and check out instructions, house and garbage disposal rule, as well as emergency contact are well documented and easy to understand.
We had great time stayed in this place. Would definitely stay here again when we visit the nearby area.
