The apartment is very well situated. You can walk to two different slopes to start you ski day. Probably for that reason, a few things could be improved in the apartment. The host and family obviously use the space when it's not rented, but they also leave a lot of their personal belongings there around the different rooms, making it harder to store ours and totally feel at home. There is also a lot of stuff in the kitchen but not what you would expect (I didn't find a cutting board for example).
The main inconvenience though is the noise. We can hear almost everything from the stairs and all the surrounding flats (fortunately, they mainly come during the weekends). The host also told us shortly before we arrived that the construction of an elevator would take place for the first week. That turned out to be extremely loud for the whole month we were there (destruction of walls and a lot of rocks and bricks carrying).
Other plus sides are the two great showers and the fact that the building is almost empty during the week. There is also a half-empty locker where we can put our skis.
