I spent a week with 2 other friends of mine in Ozat's room. The room had been prepared with everything necessary for the stay (slippers, towels, hair dryer, fridge, etc.). Despite being quite small, it turned out to be perfect for the 3 of us, both for convenience and location just 5 minutes walk from Nakano-station (metro line) and 10/15 minutes walk from Shinkuju. Ozat has proved to be an incredibly hospitable person, ready to give any help at first necessity. I highly recommend it for your stay in Tokyo.
