The building is not knew but well maintained and clean. There is a reception service where we could collect the keys and got all the necessary information. The location is superb from skiing perspective: the Cielo Alto lift is beside the building. There is also ski shop where you can buy also the skipass (sometimes crowded, be there at 8:15 if you don't want stay in a long queue) and a basic grocery shop (fresh bread) & pizzeria and a bar. The centre is a long walk or a short ride with the unfrequent bus. Note that if the lift Cime Bianche Laghi is out of operation, you cannot ski back from the Plan Maison area, you have to walk down the busterminal and go home by bus.
We arrived by car with roof rack, thus we could not use the garage spot provided, but there were many few places past the reception ~50 meters. (There are few places around the entrance, but these are cleaned from the snow weekly once, you have to leave them that time.)
The flat was comfortable for us (5 people). Well maintained, eg. there are plugs even at both levels of the bunk bed. The bathroom is new and nice, kitchenware is OK. Generally it is better than on the pictures. We liked it very well, and would came back any time.
