The Castellani Parkhotel was very accommodating. The breakfasts were huge and luxurious, the room much larger than we needed and very comfortable. We made use of the fitness room for steambaths after skiing and found the staff very accommodating when they allowed us to access it once more even after we'd checked out, on our return from the slopes before our flight back to the UK.
The walk into the old town takes only 10-15 mins but you can get bus no 3 or 8 if you're tired or cold, for just 2 Euros each. The hotel is also easily accessible from the airport, just a short taxi ride away.
