I have nothing but a great experience staying for two nights at Perry's place. The place is right by Shinjuku Gyoen -- a spectacular national garden in the middle of Shinjuku. We took a taxi from HND airport because we were arriving rather late that day. Check-in was hassle-free. You'll need to open the mailbox to get to another secure box. The host explained how to open these doors. The place itself is clean and quiet. There's a big bathtub and a washer. The beds are comfortable. I think these are memory foam mattresses. There are multiple train stations within short walking distances from this place. Very easy to get around the city and walk everywhere to get food and/or drinks. We'd love to come back here again next time we visit Japan.
