The place was cozy and quiet, equiped by complete facilities. There's also a heater in the room, but it wasn't warm enough during winter :).
We love the neigbourhood ambiance.
Also there're many convenience stores near the house, and we can walk around 5min to the higashi-mukojima station. The only problem that Station Higashi Mukojima is out of JR line coverage. So you have to buy additional ticket to reach this house from/to many place in Tokyo.
Overall, this was a great place to stay. Thanks a bunch for the host.
