Well, good for you. Maybe not so good for the neighbors in those apartments. They moved in not expecting a revolving door of strangers and late-night partiers. There's rules for zoning things, for a reason.
A conversation-starter I like to use on my hosts is to ask about their bad experiences with tenants, and most of them tend to have fairly boring ones, usually about some hard-to-please guest or another. I've yet to hear of one of the drug-fuelled late-night orgies that discussions on AirBnB seem to hold as commonplace, even from hosts who have been renting dozens of apartments for years.
Then again, I do tend to stay at apartments that are available monthly, which may make a difference.
