What is this? If you are talking about decentralized airbnb type of platform, Beetoken is working on that. Crowdvilla is also doing something similar.
I wanted to mention Beetoken too, although I personally don't like the project. In my opinion they are nowhere near competing with Airbnb, and if they somehow start to become a threat to them, Airbnb will simply implement blockchain too. I remember before ICO it was overhyped, but since then it is down (like almost everything else, but more).
