Where do actors stay when filming?

I'm curious, where do actors actually stay when they're filming a movie or TV show? Do they have dedicated housing on location, or do they stay in nearby hotels? And how does this vary depending on the size and budget of the production? It seems like it could be quite an interesting aspect of the filmmaking process that's often overlooked. Is there a certain level of privacy that actors are entitled to while staying in these accommodations, or are they more like a temporary work space? I'd love to hear more about the logistics behind where actors call home during filming.
