Most ski areas have an accommodation section on their website which lists all types of accommodation in the area ( the areas can be extensive) You may find the exact same accommodation listed there....sometimes minus platform fees and ,sometimes including cancellation at more reasonable , or no, extra cost.
Edit,
I should have mentioned as example, I'm going to Austria this week and the local accommodation platform got me the same place for €140 less than Airbnb.
Airbnb can be a great search engine , but once you find something that suits, consider that the start of your search.
