What is your recourse if you do happen to find a hidden camera? I mean, is it illegal for someone to hide a camera in their own house and not tell you?
I ran into a situation where there was an undisclosed camera inside a room I rented (with the bathroom in its field of view, no less!). It put me in a tough spot because in an unfamiliar city, I don't want to cancel my room and have to look for another, but I also don't want to be spied on either. I covered the camera and disclosed it to AirBNB after the fact. I'm not sure what happened to the hosts, if anything.
For this kind of offense if you are uncomfortable staying any longer, Airbnb can try to relocate you in a similar priced listing for the rest of your stay.
In any case you should also say so in the review so other guests are warned. The host can't see your review until after they review you themselves.
It depends on the state but almost every state has a law saying something along the lines of areas that have elevated natural expectations of privacy - rooms such as bedrooms or bathrooms a reasonable person could expect to have total privacy - cannot be recorded without the consent of every single person in the room. So, in general, yes.
BTW, some states have laws that extend this to an entire living space, including kitchen etc.
