@Cory159 "Entire place" on Airbnb means the guest has a private unit with its own entrance and no shared indoor spaces with the host, except perhaps a laundry facility. It doesn't mean the guest has rented an entire house unless it says that.
It could be a private studio in the home, half a duplex, perhaps the entire basement or bottom or top floor of a host's home.
What "Entire place" indicates is that you have privacy within the unit you have rented- you don't use the same outside door the host uses, or the hallway, or the inside house stairs through the host's living space. You have your own private bathroom and probably a kitchen or kitchenette.
Beyond that, the host should make it clear what the living situation is, and the guest should ask questions before committing to a booking if they find the listing ad confusing or need clarification.
