I loved the service back in the early twenty-teens, but I had a strikingly bad experience with a home I tried to book in Boston.
The owner found out her home listing had rats a few days prior to check-in, and admitted to not being able to get rid of them fully before the date, leaving the possibility of rats getting poisoned/killed by the traps she set up. All of the communication was via @airbnb.com emails I had responded to, but Airbnb's support couldn't find any records of these messages. It took multiple calls and entirely too much effort to get an eventual refund plus a tiny credit on their site -- not nearly enough to book a replacement property that close to the date anywhere within city limits.
Meanwhile, like I mentioned, the prices of properly licensed and managed vacation options have become competitive with Airbnb while offering more reliable and flexible wrt date changes and cancellations.
