It was the perfect stay. Norihito is very welcoming host. He responds very quickly (in japanese, but that's not a problem having google translate) and didn't have any problem with the check-in after 10 p.m. (due to our delayed flight). He provides a lot of useful things - portable wi-fi router, towels and even some food. His apartment is well equipped and the room is very spacious and comfortable. It's pretty close to the subway.
