We spent 3 nights at Aki’s place and it was a nice experience.
She welcomed us very late at night when we arrived from the airport and showed us around the house, detailing all the rules (there are quite a few!)
The apartment is located at a 15 minutes walk from the nearest train station, which isn’t on the JR network, so it can get expensive to get to town often.
There is no kitchen access but guests can have hot water for a tea.
Overall it is recommended.
