And yes, I use Airbnb as a guest as well, but I gauge the risk of having a bad host into the decision making.
We also get all type of horror stories from guests that had a bad experience and found themselves trying to find a last minute place to stay.
The problem is that the Airbnb app heavily disincentivizes "professionalization". They have a small cartel of PMS providers that can actually hit their API. I can't build my own systems on top of their API, I have to go through a middle man or use the their crappy app.
Their app is so incredibly obtuse that it puzzles me how people shower Airbnb as a "great product design company". It's a beautiful app sure, but incredibly clunky. It's like a call center phone menu made into an art piece.
