AirBnb had to fight a very similar path and the only bad press I can remember about them was that tone deaf/ offensive political marketing campaign they had.
Headlines like "Airbnb hosts violently murder houseguest, police say" have stuck with me.
AirBnb have their own issues, and plenty of bad press about cities popular with tourists crumbling under the load AirBnB are causing on their communities.
There's been several articles about them shafting apartment owners, offering very little from their "insurance" for trashed apartments. In most cases the renters are sane people, but if you get the drug-fueled orgy, you can probably safe in betting that AirBnB will not compensate you for the cleanup.
They also spammed Craigslist users (violating TOS and basic manners) with emails from bots pretending to be women.
