Airbnb markets it as you have access to the entire property as in an entire house. If you’re traveling with a family this is ideal but really hard to filter out if they let all sorts of apartments show up as an entire house. I believe they have or had a filter for apartments but honestly their search is really hard to get exactly what you’re looking for. The other thing you see is “entire home” actually being a bungalow in someone’s backyard.
