Just finished a two nights stay here, and it was wonderful. The landlady was very nice and attentive, and the food was wonderful.
It's a very traditional building, and for a first time visit to a Ryōkan it definitely set a high bar for the rest of my trip.
The roads around are fairly narrow, however local drivers were very considerate and I didn't have any trouble. The local castle is a treat, especially getting a view of the mountains from it's peak, and is walkable.
