And yet, you stay in them.
Also, while I'm not OP, I gave up on Airbnbs a long time ago for the same reasons, and that impression is occasionally refreshed when I stay in an Airbnb that _someone else_ arranged. I will go out of my way to avoid them if it's all up to me.
The major travel sites all push you to multiple rooms - but lots of hotels now don't have "adjoining room" access (compared to say 30 years ago), and in one case, our 2 rooms were on different floors because of check-in time.
The travel sites are picking up on this and competing with airbnb as well. Typically my experience with those rented homes is a) cheaper than airbnb and b) better service. However, I'm sure they are the same type of superhost company that would be banned in Barcelona.
