@Emiel1 Of course Cheyenne will have to answer as far as her specific listing goes, but my understanding is that "entire house" doesn't necessarily mean that every room is available for guest use, as long as it's made clear what areas are off-limits. What it means to me is that the guests won't be sharing the space with anyone, they will have complete privacy, and of course if you advertised an entire house, you couldn't tell the guests they couldn't use the kitchen or living room and you couldn't advertise it as 2 bedrooms if one of those bedrooms was off-limits. I think many hosts have a locked storeroom on a whole house listing, where they might keep extra bedding they don't want the guests to use, perhaps giant packages of toilet paper and other supplies they don't want the guests to just be helping themselves to, or a locked garage that isn't for guest use or access.
As I read Cheyenne's original post, the camera was in the locked room, not anywhere available for the guest's use.
