We stayed for half-term, 2 Dads and 3 teenage kids so there was plenty of space for everyone. Our first impression was how clean the apartment was with beds all prepared and plenty of fluffy white towels available (very unusual for French rentals). The only items that weren't there that we could have done with were bathmats (which were subsequently delivered) and tea towels (fortunately we had one packed).
The 3 double bedrooms are of a good size, and my boys enjoyed the alcove room with 2 sets of rustic bunk beds. Being teenagers they did complain that there weren't any sockets in that area to keep their phones and ipads running, but probably a good thing !
The rest of the apartment is very well equipped with cupboards, large fridge freezer, convection hob etc.. Even a washing machine that we didn't use. Just be aware that there isn't any TV, just a TV and DVD player.
Our only real issue was that the small lane to the entrance to the apartment was very icy so we couldn't drive up it. The apartment is on the 5th floor at the far end to the entrance and unfortunately the week we were there (including when we arrived) the only lift was out of order more often than working. A minor irritation. The technician seemed to be there constantly and as soon as he had it working it would break down again.
The apartment is very convenient for skiing from the door - don't walk up to the bubble but ski down to main chair in Les Coches. Whist we were there the snow conditions were superb, but the weather was a real mixed bag - snow, wind, fog, rain(!), and some very nice sunny days. If planning to take the Vanoise Express over to Les Arcs be aware that there is a single chair to get our of Peisey which was a bit of a bottle neck. We loved the runs through the trees back down into Les Coches which were in perfect condition. One of my sons managed to find many different routes down off-piste between trees.
On the rainy day we took the bubble down to Montchavin for lunch which was well worth it as it's a lovely traditional farming village with good old farmyard smells and cows in basements below luxury ski chalets !
We ate out in Les Coches a few times, La Poya being our favourite for traditional Savoyarde cuisine. Note that we walked up and down to the centre which takes about 15 mins down and about 20 back up.
Overall a great stay and we would highly recommend Heather's apartment
