Our experience was amazing! It was wonderful to be greeted by the owners and taken care of by the staff. The location is superb, the rooms are modern and well-equipped. The view is just stunning, overlooking the mountains and the village. It was a nice bonus to take a cable care ride for free and enjoy the views from above. The spa offered a great variety and a relaxing jacuzzi. We had dinner in the restaurant and it was delicious with great service.
