> "The Berlin Senate’s ruling nonetheless reflects a general feeling across a city in which homes are getting harder to find: Berliners have had enough and they want their city back."
Translation: There is no pricing mechanism on rents in the city and it is becoming increasingly impossible to find an apartment.
While it's certainly true that AirBnB essentially allows landlords to flout the law, it's worth noting that the adverse effects of price ceilings on supply are the root cause of Berlin's problems and this will not solve the underlying problem of rents being far from equilibrium.
Maybe there is some other cause (e.g. everyone wants to live in a city now)?
