We visited Sestriere Feb 2013 staying in the Hotel Belvedere which I could recommend: excellent food, clean room and top service with free mini-bus to and from slopes all day.
Snow conditions: perfect and we skied most of the Milky Way in a week. Lift pass prices are a bargain as well as ski and boot hire but the piste markings are poor and not very well signposted. I still find it hard to believe that an Olympic resort still relies on antiquated chair lifts and a dreadful button lift for its major links to other resorts including Sauze and Montgenevre. The mountain restaurants are priced very reasonably unlike their French couterparts. All in all, this is a good skiing location for intermediate and beginners with not too much for the advanced. We booked with Inghams but sadly they have now succumbed to employing cheap Eastern European reps with poor English and no banter, never again.
