We rented a chalet for a group of 14 people (university students) through Chalets Montmorency and were blown away at how convenient, comfortable, and close to the hill our place was. We were able to fit in everyone comfortably, even in the common areas for apres-ski. The chalet was having some work done on it, so there were a few small "repairs-in-progress," but nothing that caused any discomfort. It's not the Ritz, but met and surpassed our every need.
The chalets are within walking distance (about 20 minutes) to the ski hill, or about a 2 minute drive away. There's a town nearby (about 10 minute drive) where you can stock up on provisions (including an SAQ ;), and Quebec City's a stone's throw away.
Can't recommend this place enough...great bang for your buck!
