The hotel is located write in front of the bus stop. However, it is not near that near Kamikochi bus terminal (5 min by bus, or 40 min walk). In my opinion, Taisyoike Pond is the most beautiful location in Kamikochi and staying overnight allows you to see the beautiful scenery during the evening and morning when there are less people.
The room was spacious and enough for 3 of us. The staff were helpful and could speak english. We had dietary preferences which they catered to. The food was very good too, there was a lot of food for dinner and we struggled to finish it.
The only thing was that the public bath was kind of small. There are only 4 showers and the bath was quite small. It was very crowded when i was there in the afternoon.
