Platforms like AirBnB only put oil in the fire when it comes to housing crises.
AirBnBs I've stayed in the past few years have all been janky, weird, and not really any cheaper than hotels. I don't have to do chores at hotels, and I can always get (and return) the key promptly. I've also been told on several occasions not to let anyone else in the building know I was an AirBnB guest. AirBnB used to be better, but the advent of "professional hosts" with many properties really degraded things. They often have the typical landlord mentality of expecting a lot of reward with little work or risk.
And yet, you stay in them.
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.
