The location is unique and extremely beautiful but the the hotel structure is designed for Summer, Spring (maybe Fall) but not Winter season.

I found especially problematic the Spa area, with the locker/changing room in a separate building from the Sauna/Steam room structure, substantially forcing you to walk outdoor with only a robe on. Also, due to the large wooden doors of the Sauna/steam room building, with people entering and exiting, there was a lot of cold air circulation in the rest area.
Another downside is the air heating system in the rooms that can't warm the concrete floors (very cold despite a few rugs) and that is running almost constantly night and day if you want to have a warm room.
There is a beautiful heated pool outside, but again I would have expected, with low temperatures outside, to have a changing room near the pool or even with access to the pool (any temporary heated structure could work) to make the experience more pleasant and accessible.

Food was good but I hoped to try more local recipes (especially for breakfast - very good homemade pastry!)

The staff is extremely kind, well trained and discrete. Best part of the experience for me.

Also the hotel provides a number of great activities (from Yoga to hikes to workshops and shows), all worth trying.
