Ohkubo's place is located in a quiet neighbourhood yet very accessible to public transport and a good range of restaurants (some 24hrs). Ohkubo san is also very hospitable. We met him when we checked in. He helped us with our luggage (because we have young children) and he walked us all the way to the sushi restaurant that he recommended. He also wrote us a welcome note with welcome gifts. His place is also well equipped and clean.
