We stayed here in Jan 2011 with the Tignes deal offering free accomodation with lift passes bought in October. Wasn't expecting much for free, but it really was ok! We were 4 people, and had just 18m2 of apartment - literally 2 bunks in the hallway, sofabed in the living room/kitchen area, bathroom & balcony. Just about enough room for 4 people who get along (but barely any privacy for those that don't)
Location was good - not ski in, but easy walking access to lots of lifts and the fenicular to the glacier. Good central location with plenty of bars and restaurants a short walk away, relatively quiet at night. Parking available in the open air just outside the carpark, or we unloaded there for free for 30 mins and then left the car up at golf parking under cover for the week.
In summary, small & basic but adequate, and in a good location.
