At AirBnB's current scale this actually causes an annoying problem. It seems they have a non-negligible effect on the cost of rent. Since AirBnB does not have the requirements listed by the OP above they are able to operate at a lower cost and capture demand that would have otherwise gone to hotels. This demand then fills up buildings that were originally intended to be multi-family residential buildings and are now effectively being used as hotels reducing apartment supply and driving up cost.
