I have a bungalow with a front door I normally share when I host. Guest then take a few steps to stairs going dow to a basement apartment. We have been very successful with only one guest Stating they thought the entire apartment meant entire house! I’ve since screened off our private area so that guest don’t feel obligated to converse if they would rather not.
our current guest is an essential worker that has remained with us two months now. She simply uses the back door which opens up into the same shared hallway before going down to the apartment (that has its own front door ). This works for us.
