Michiko-san's house is located in a very convenient position, close to Oji station (on JR Kintetsu line and metro Nanboku line). The bedroom is on the ground floor and furnished in traditional Japanese style (tatami mats, fusuma, and futon beds). The hosts live in the same house, on the first floor, but we had exclusive use of the ground floor bathroom, shower room, and living room with kitchenette. We were thankful to find free bottled water and clean towels the hosts had prepared for us. Overall, the house is pretty big by Tokyo standards and good value for its price.
There was only one major downside: while the bedroom and living room were reasonably clean, the bathroom and shower room were dusty and moldy, and looked like they had not been cleaned in a few weeks. We spent most of our time outside, so we could live with it, but I know this may very well be a dealbreaker for some people. I hope the hosts can use some of the proceeds from our stay to hire a good cleaning service and get the house in tip-top shape for their next guests.
Despite living just one floor up, the hosts respected our privacy and never intruded in our spaces. We never actually got to meet Michiko-san, but her husband came to pick us up at the station and was kind enough to drop us off again at checkout, even though it was very early (6:30 am). We appreciated his thoughtfulness very much.
