I used to use Airbnb quite a lot, but now do so as little as possible. One reason being having seen the effect it has had on communities in some places, pricing out locals, noise and disruption etc.
But also be because of numerous issues I have had with them, which have been more frequent recently.
These include significant price rises after booking and paying, despite Airbnb saying this is not allowed under their own terms.
Airbnb refusal/failure to get an owner to change a totally misleading description of a property despite numerous attempts (reported listing, sent emails, reported to ASA, called them out on twitter, Facebook). For example the property listing said it had fabulous views of two local landmarks - it was a basement flat so had no views of anything except a brick wall and a dirty storage area. Numerous other misleading and false claims in description. Got terrible reviews (unsurprisingly) but then was relisted again for this summer season as a new listing with exactly the same photos and misleading description, only a change of host name. Not the first listing I have seen on there which has got rid of bad reviews by relisting under a different host name, even though this is not supposed to happen.
Properties are supposed to declare cameras etc in listing as per Airbnbs own terms. Place I stayed at had a webcam/ security cam in hallway facing front door which was not declared. Felt creepy being watched every time I went to my room, to the bathroom, to the kitchen or entered/left the property. Airbnb didn't seem bothered about the non declaration.
Had issues with an apartment in France, key to building entry would not work so I was locked out every time I left. Host not interested, just said keep trying it, denied there was an issue then admitted there was but they thought it had been fixed. Locked out and desperately trying to contact Airbnb and left messages with dying battery, they still hadn't replied by the next day, so if a neighbour hadn't let me in I would have been stuck outside an apartment I paid for, all night in a foreign city, on my own with a dead phone.
Numerous other issues, including cleanliness (lack of) of some properties.
That said I have stayed in some very nice places, but most were some time ago, not as many recently.
Have noticed price rises too, so it's now seldom the cheaper option it used to be. In fact the same property listed on several platforms is often more expensive on Airbnb than on hotels and booking dot com, even though those two sites charge 15% minimum commission to owners and Airbnb charges 2% I think (plus Airbnb fees are paid by the guest, not the property owner).
The reviews also seem to be more positive (too positive) than on other sites, for whatever reason. Have stayed at a few which had undeserved rave reviews.
