My wife and me spent 3 days here in July.
Ponte di Legno and surrounding mountains were amazing and the hotel did not let us down. We were not interested in spa and other facilities so our judgement is entirely based on the room and breakfasts we had there.
Room was spacious, light, nicely furnished and clean. No problems at all. No air conditioning but opening a window to let the air in is enough. Hotel is far enough form the quite rumorous mountain stream so that its distant sound did not disturb sleeping.
Breakfast consisted of all those things we are used to and which you would expect from the well managed hotel. Nothing fancy, possibly could be improved with more diverse or more interesting offer, but generally no major issues there either.
Many hotel features must be very useful for the ski tourism - no carpet on the ground floor corridors, ski room, tv room, games room, huge chill out area around the bar.
