We went to Kamiya's place by car. The parking was easy to find and it was 1min from the Airbnb.
The interior was clean and new. The large shower room and the hot tub was amazing! Even all the soaps smelled great and it felt like a private hot spring.
Since we went in December, it was pretty cold outside and the first floor didn't warm up despite having the heater on all night. For the second night we decided to sleep on the 2nd floor, which has a king size bed and that was wonderful, Nice and Warm!
I would definitely stay here again and recommend this place to anyone who wants to enjoy nature and have a private hot spring experience!
