Had a great time at Koichi's apartment - highly recommended! It's in a quiet neighborhood but not far at all from where all the action is as well as public transportation. The host was excellent when it came to communicating with me and was kind enough to stop by and say hello after we checked in. He gave us cookies too! Koichi also was helpful in allowing us to check in early, as we were arriving to Tokyo earlier and his other guest was already out of the apartment. Pocket wifi was great to have as well. For a great experience at a great price, definitely check his place out.
