A couple of things to note. First you need to bring your own bedding, and second you are expected to clean the property yourself before departure.
Looking at the pictures, they are very accurate for what you are getting. The biggest positives are that the price is good value, the property is clean, and you are located right beside the ski rental shop and one step further to the pistes of La Rosiere and Thuile!
Be noting that La Rosiere is a beginner's slope. You shouldnt come here for black runs. They were all closed down! However, if you are arriving by car, Les Arcs (which is amazing) and Tignes are close by and well worth visiting.
