@Buzzard, the long overdue reply re Serre Che.
As others have mentioned, it’s a town, then a string of villages along the road. So, broken down in bite size chunks;
Villages
Total beginner – Villeneuve. Easy access to Mickey, right by the village.
Intermediate/Expert – Monetier or Chantemerle. I prefer the latter, as it’s easier to get out to to the biggest mix of terrain.
With a non-skier? Stay in Briancon. The lifts out are a little clunky at times, and the pistes back down can be icy, but you’re skiing from a town!
If you decide on Chantemerle, which you should, the Rocher des Hameaux Blanc is lovely. http://www.peakretreats.co.uk/winter/ski-resorts/oisans/serre-chevalier/le-hameau-du-rocher-blanc Right in the middle of the village, nice pool, parking etc. Very much recommended. I can probably find you some personal connections with places over there as well if you like, but would be good to know budget (They’re not the cheapest places!). FWIW, we stay at the Plein Sud. Lovely hotel that feels more like a chalet. Very friendly place, with excellent staff, delicious food and a nice location too. The bar is a lovely place to while away the aching legs, too. I know it’s not an apartment, but it’s just plain lovely. It’s a ski hotel, not a luxury palace, but that’s what I love about it.
Also, Turin is indeed the best flight. A nice quick transfer (Assuming the big old boulder around Monte has been moved by now!)
