I don't know who cares of a party in a flat. Noisy parties existed before airbnb.

To me, the problem is that since there is no regulation, renting a flat for short periods allows to make much more money than renting it for a long time to a reasonable price. It contributes to the shortage of flats to rent supply, the rise of the rent prices and gentrification.
