Mary's place was great, we'd definitely recommend staying here if you're in Tokyo. The neighborhood is really interesting and hip but quiet. Mary was an excellent host and she helped us out by letting us store our bags for a few hours as we were very early. The apartment is nice and adequate for 2 people. The fold-out couch was as comfortable as most fold-outs but there's so much walking to do in the area that I was too tired to mind! The little outdoor courtyard is a nice touch.
