I came to the Carlo Magno for a conference in January. I thought the place was sensational, one of the best places I've ever been to, not sure what's up with all the poor reviews! The food was some of the best I had in Italy, workers were nice. Swimming pool very clean and neat. Rooms weren't super fancy but very very clean and the bathroom is spotless. Right next to the ski lifts. I got a discount on the rooms through my conference, but I would come back in a heartbeat when I have more money some day.
