This Chalet is run by Alpine Elements and seeing as there's nothing on Tripadvisor I'd thought I'd give some detail for those people potentially booking it.
First thing to be aware of, is that this is the last drop on the coach from Geneva. It takes roughly and hour to get to Morzine, and then you can add 45 minutes at least to get to the chalet. It's not a big deal, just we weren't aware of that.
Second major thing to be aware of is that the lifts nearby are not included in the local Morzine lifts pass. You'll need the full Portes Du Soleil pass. Alpine Elements lied to me about that. Now you know. Their free lift pass is the local one, so you'll need to upgrade at a cost of 60 euros.
That said, it's in a fantastic position. The telepherique is open until 8pm weeknights and midnight at the weekend. There is a free bus that runs into Morzine, and a taxi back will cost iro 20 Euros. If you're a capable skier/boarder then I recommend taking the chairlift rather than the telepherique. By skiing one, failry steep red, you can be at the top of the mountains above Avoriaz and enjoy some brilliant runs into the town. It's quicker too.
The Chalet itself is basic. Very basic. There is just one decent bathroom to share between up to 12 people. There is a shower in the basement (which isn't nice) and a bath on the 'ground' floor. The hot tub is in the garage. The kitchen is tiny and it's a wonder the hosts can cook a 3 course meal for 12 in there. Quality suffers.
