Nice house. Fully renovated with brand new bathrooms, kitchen and other amenities. Two bathrooms: one with a bathtub on the 1st floor and the other (a shower) on the 2nd floor. Great location, at about 8 minutes walk to Shin-Okubo station on the Yamanote line.
Ruby, the host was very responsive and so nice. Her husband drove us to the station after the check-out.
The only issue is the noise isolation. But it is quite normal in Japan as every Japanese old houses are not isolated so you hear everything from outside. I suggest you to use ear plugs if you don't want to be waken by the garbage truck, cats or even people talking. But I will still recommend this place because of Ruby's great service and the location.
