It was very nice originally, when they sold themselves (at least in the EU) as a way to stay "at home", even share some time and meet the locals renting you their room, all for a fraction of what a hotel costs.

But soon enough they diverged from that into the "whole buildings bought by deep pocket owners to build apartments for Airbnb" thing that hurts neighborhoods and is a net negative for cities.

Also now with the big service fees they charge, I usually just prefer avoiding Airbnb altogether. Between their +80€ creeping up from nowhere after having chosen a place, and the "cleaning fee" (for nothing because owners will just clean a bit) that ends up being another +50€ or so, makes most places I see in Airbnb hardly competitive against hotels or proper tourism-approved apartments in other platforms.
