Though in the central part of Tokyo, it requires a bit of walk (10 - 15 mins) to the nearest subway stations (either to Asakusa bashi or Ryogoku stations). Hidy-san's house is in the quiet residential area and it's safe to walk in the dark. We worried that we might create inconvenience to Hidy-san as we were sharing the same house with him, but Hidy-san was not around most of the time thus we actually occupied his house like private rental. :) We finally met Hidy-san on the 3rd day morning and had a lovely chat with him. We recommend this house to other travelers and would definitely reconsider coming back here if we visit Tokyo again!
