This place is OK if you are young and don't mind skiing or boarding without any sleep. It's noisy, not just from 'auberge de jeunesse'-type guests but also from piston bullies on nearby slopes (this of course means you're close to them, which is good).
Upon arrival we were told we couldn't check in until 5pm. Fine; we went downstairs to check our bags into left luggage. When we had lugged our stuff downstairs (lifts out of action due to 100s of guests milling around), we were told with a Gallic shrug, <<il n'y a plus d'espace>>. oooook. As we have a 3 year-old, we chanced it and managed to get the keys for 4.30pm. There was otherwise nowhere to sit or stand.
The room is small and very basic. As a veteran of Center Parcs' variable standards, I am used to chipped pine and mildew, but the room is dirty, especially the bathroom. It is pretty insanitary, and we are not all that het up about such things. You get a great view of the crusty toilet when sitting in the bath, but at least there is a plentiful supply of hot water whilst admiring the view, and smell. And if I had a) thousands of crusty teenagers tramping their ski gear through the corridors and b) Plentiful negative reviews on TA, maybe I wouldn't bust a gut to clean either.
It's not a place I would recommend for small kids. Lots of swing doors and bad lifts blah blah. But it was available at short notice for our skiing trip, and there are good facilities in terms of the bar, restaurant and supermarket in the building. It's convenient for lower Thorens, though those seeking a bit more bar action may prefer upper Thorens. The building is cavernous and the elevator system merely bonkers, but once you accept that you will never understand why L is the top floor and C the bottom (and why one lift riser is two floors shorter than the other), you get past all that.
I wouldn't come back. Ever. But when it's -20 outside, really you're just pathetically grateful that the Place is warm.
