We stayed here for a week. You cannot find a better value for Tokyo! Mitsue was super nice and kind. She even offered us some good food throughout the stay. We only regret that we were so busy we couldn't see her more! The room was private and very comfortable for the two of us, and very clean with many amenities. The futons were comfortable and it was nice to have them to sleep on! The apartment was a 3 min walk from the station (on the JR Joban line which turns into the subway Chiyoda line), and you can get most places in Tokyo within 30-40 minutes door to door. Some places, like Ueno and Kita-Senju, are closer! On Friday and Saturday, you can hear noise from the izakaya and people enjoying themselves, but we didn't find it hard to sleep through. There is a fan we used, and it blocked the noise just fine.
Overall, we cannot recommend this place enough! It was a perfect stay and we really enjoyed the place and Mitsue's hospitality. You'll regret not staying here!
