My husband I stayed at Y's Inn Nakai for 15 days in May. It was for the mandatory quarantine after returning from the US, and the place turned out to be perfect for us.
With well positioned windows and the white interior, the house feels open and airy despite its size. It's free of clutter or kitsch. It was nice not to feel cramped.
Having three floors all to ourselves made it possible for the two of us to set up independent work space. The Internet connection was strong and we could conduct online meetings as well as catch up on shows on Netflix. We cooked our own meals and did laundry on sunny days. Going up and down the stairs throughout the day turned out to be good quarantine exercise.
Being new to Airbnb, we ran into a few problems at the beginning, but the host team was always gracious and responsive and helped us out in each situation. (We only communicated in Japanese, written or spoken.)
If we get to return to the Nakai area, we look forward to trying out a number of small neighborhood restaurants that we saw.
