Well did you report them to the proper authorities ? ( the organization managing the building, the city the cops ), because I can assure you it will shut down any illegal hotel quite fast.
There's plenty of news stories on the Web of neighbors complaining of houses advertised as "party houses" on Airbnb with multiple parties a week many with police involvement including a police helicopter. Clearly Airbnb has doesn't do much to discourage this activity, even when the problem is well known.
Yep, exactly as recommended to others: police and council. This is why you need to invoke them early: you'll need to establish a documented history of anti social behaviour.
