Shin's place is a unique experience, it makes you feel like a kid again climbing the diy "staircase". The space is pretty tight (we were a couple and slept on one floor but possible to space things out across two floors) but it's clean and well equipped for basic needs. Close to shops (family mart and 7-11 a few mins away) and hatagaya stn is a short walk away which is just a couple stops to shinjuku. Shin also provides a lot of useful info and guides to the area, and breaks down very clear directions on how to get to the house. Great place for those looking to stay somewhere a little bit different, but not for folks with problems getting around/recent injuries!
