I ve used a site that was mentioned on here but can remember what it’s called . I’ve just looked at air b and b for a ski Appartment and think their fees have gone silly .
This one?

Maybe https://www.abritel.fr/
Pierres et vacances? they do a lot of ski apartments, but they are nothing like air bnb, and have been around for years and years.
Without a name or an example of what you think is wrong, its a bit of a pointless post......
