We (family of 4) spent 5 nights in the Cervino building.
Pros: the location was perfect, the apartment convenient to spend time before and after skiing, have simple meals, spacious enough for a family with 2 kids. And clean.
Cons: the whole place would need some refresh, the absence of any internet service is unacceptable per modern standards, information from staff was poor (we had to figure out where to put the trash or the skis), most amenities are for a charge (pool, parking), noise isolation typical for buildings of that period.
But overall our stay went very well. And La Thuile is a top notch place!
