Though this place may not have the most convenient location, we were able to taxi here and there to make up for it. The one interior room is really cool - like something out of a period drama - and all the other rooms are sparkling clean. The building seems a bit older, but was perhaps recently renovated. We had a beautiful view of Mount Fuji our first morning! The host answered all inquiries quickly and was very friendly. It was more than enough room for our small family, and our infant son slept well at night.
My only word of caution may be that the bath area is rather cold in the winter, though there were space heaters to make it more comfortable. It may also be rather hot in the summer. This is the same for any older style apartment you might stay in (and many we rented in our 10 years living in Tokyo), and not a turn-off imho if you know what to anticipate.
