I've had the exact opposite experience. I always book from well reviewed hosts and have never had a bad stay.
We always travel with our kids, so multiple attached bedrooms is important, and something you pretty much cannot find in hotels without spending obscene amounts. Most hotels won't even guarantee consecutive rooms, let alone attached.
Just dealt with this recently and up until then mostly had great experiences with hosts. When something goes wrong (ex: had a family emergency that blew up my travel plans a couple of weeks out), any refunds or resolutions are at the discretion of a host who is directly financially affected by the outcome. So there's never an incentive to be reasonable, and they'll often get hostile or combative - in this recent case pretty much immediately. I was able to easily alter/refund every single component of my trip, including a hotel stay, but couldn't do anything about the AirBnB because the host dug his heels in and started getting hostile.
