The apartment is just as shown in the pictures, tiny but cozy. We spent 3 nights with our two kids, 11 and 13 years old. You have to unpack carefully and store things under the bed, the bench, etc, but it was fine for us.
It is great to have so many things in the kitchen, many free (good olive oil, vinegar, salt, sugar, spices, breakfast stuff, etc) and many that you can use and pay for (pasta, olives, snacks, etc).
And it is also great to be able to leave the house with the skis on, the ski slopes being just 10 m from the door.
Great view from the balcony, of the Grand Muveran and the Dents de Midi.
The restaurant just down the hill is very nice, with friendly staff.
The manager of the apartment was very responsive, before and during our stay.
Only problem was that the apartment was not ready at 4pm as promised, but 1.5 hours later, because there was a problem with the cleaning lady (not the first time it seems... must be hard in high season), and the manager had to do the cleaning himself.
Overall we loved the place and would come back anytime!
