I stayed at the Bonapace during the last two weeks of December. The hotel was fairly empty until December 22 when they had the Ski World's Cup. Very pleased with the owners and their staff. They were very friendly, and could speak English well enough that we could converse. The room was a nice size and had a spacious king sized bed. The closet was spacious - had lots of room to had clothes and shelf space too. The room was very neat and clean. The staff was always helpful. Room was promptly and thoroughly cleaned every morning. Ate breakfast there every morning, nice assortments of pastries, meats, cheeses, hard boiled eggs, coffees and teas. We did not have a refrigerator in our room, but it was very convenient (and cold) to open the window and store our beverages and yogurts on the ledge.
I am not a skier, but it appears that they have beautiful ski slopes, and Madonna di Campiglio is known for their skiing. The town is very nice and fun to explore. Lots of upscale shopping, nice cafes, and wonderful restaurants. Everything is within walking distance. The people in town can speak English fairly well, so you will be able to converse even if you cannot speak Italian.
Multiple bus stops within walking distance so you can explore the other towns in the area. If you take the bus to Trento, you can hop a train to many cities in Italy, such as Venice, Rome, and Milan; it is also a great way to explore some of the smaller cities such as Bolzano or Verona.
