I'd wager that most AirBnB stays are one-offs on vacation. Home cleaning is recurring, making it more vulnerable to the "here's my phone number" weakness.
AirBnB's that business now. They used to claim they were only a matchmaking service and any risks were to be worked out between the homeowner and renter, but after some really bad publicity c. 2011, they've really doubled-down on customer service and insurance. Everyone I've known whose had a bad experience with AirBnB lately has had it turned into a good experience.
"Everyone I've known whose had a bad experience with AirBnB lately has had it turned into a good experience."
Minor nitpick on this... it's doubtful that it 'turned into a good experience', as much as "AirBnB was able to compensate, monetarily or otherwise, for the bad experience (which still exists)".
