Relative wants to AirBNB spare room in her house

She’s 68 years old and lives alone in a small house in FL. She wants to use one of her spare rooms to have an AirBNB out of her house for some extra income.

She’s excited about the money but I think it sounds like a fuking retarded idea to have a revolving door of strangers in a house you live in. What do you think, misc?
