We booked a last minute break in the 1 bed apartments. Normally I'd go for at least 2 beds but thought we'd try it out (2 adults, 2 kids).
The 1 bed apartments are small, but do have everything you need. I was pleasantly impressed with how modern it felt. There are 2 beds in the lounge area which pack away easily.
Location wise is pretty good for ski school (allow 7-10 min walk, quicker if there is snow). Getting down into town is a 3 set of stairs job, but if the escalators aren't out of order, it's not too bad on the way up.
Avoriaz as a resort is good if you get the snow but it does feel quite spread out - the walking became a bit tiresome for small feet. I felt the dining options were also a bit limited. For skiing with a young family who are just learning to ski, I'd suggest Les Arcs 1950 where Pierre V. also have properties. More
