Great place, quiet neighbourhood for a goodnight sleep. We stayed at Mariko's 15 days and felt at home. Would recommend for exploring Tokyo at lenght.
The flat is not easy to find following the google translated info in the description and google map points to a big building site. However it is very easy to find if you just remember to turn right in front of Daiso and keep going straight until the juniur high school and the cherry blossom mural on the right!
