Chiara's place was great to stay in for our family. It is very near the main gondola for the slopes, and the flat itself is on the ground floor, so really easy to get in and out of in ski gear.
The flat is well equipped for self catering, and there are supermarkets nearby.
The resort itself is great for families, and really not crowded, we hardly stood in any lift queues even though it was UK half term.
The ski area itself is not huge, but if you are skiing with young children that doesn't really matter. Because the lift queues are never very big, it means that they still get lots of ski practise, and not too much standing in queues getting bored.
