Mr. T and Koji were wonderful hosts. They were super friendly and helpful during our stay. They recommended some nearby restaurants, bars, and coffee shops, and offered to take us out drinking one night. Mr. T came by every morning (around 9:30am) to drop off fresh towels and take our used ones. They even brought us some orange juice one morning and also drove us to the subway station on our last day so we would have a direct line to the airport.
The apartment was beautiful. It looks exactly like the pictures. It's located in a small and quiet neighborhood, but it's a short walk to the nearest subway station. The apartment has WiFi and they have a portable WiFi hotspot available to rent (500yen/day + 500yen).
If you're looking for a quiet place outside of the busy city I can't recommend this place enough.
