We enjoyed our stay at Han’s place. There is a convenience store located nearby his house as well as 24-hour dining options around Ostuka station. All the information provided is accurate. As not all stations in Japan has escalators/lift, we were delighted knowing that Otsuka station has an escalator, there is also a lift up to Han’s place. I would definitely choose to stay at his place for my next Tokyo trip :) thank you very much! It was a pleasant one.
