This chalet is a real home-from-home. Very comfortable and clean with everything you would expect and more. The best thing about this chalet is its location: if you want a chalet in the town, you are five minutes from the shops and restaurants of St Gervais AND the bus stops immediately outside the chalet to take you to the main Bettex ski lift. We hired ski equipment from a shop up the mountain and left our equipment in their locker room after skiing each day, so sometimes did the ten-minute walk to the lift instead. The bus runs every twenty minutes in low season (but beware, it doesn't stop at the advertised times, but precisely five minutes before them - so 15, 35 & 55 past the hour).
The damage deposit is high but I think this is because the chalet does feel like your home and there are some nice furnishings. Although also rather high, I would recommend paying the cleaning fee because according to the contract you need to leave the chalet exactly as you find it and to do all that thorough cleaning while you are trying to leave for a flight in the morning would be a challenge.
We flew to Geneva and got a private minibus transfer with Alpybus which was good value and took one hour. Once in resort, if you plan to ski in St Gervais each day there is no need for a car. ESF provided excellent tuition for children. It is easy to reach the public swimming pool on the navette bus (or on foot if you don't have small children with you) but on a totally random note if you visit the pool, take your towel all the way to the poolside with you as it's a long walk when you're wet and cold (and naked, as for some reason the six-year-old was by that stage). It's also easy to reach the Bains de St Gervais, which aren't in St Gervais but in La Fayet which you can reach on the Tramway de Mont Blanc (station very close to the chalet).
