Airbnb settled with the two cities to provide hosts’ information and to delist those who aren’t registered, and the Boston agreement also notably requires “fairness across platforms.”

This entails efforts to level the playing field - not so much among short-term rental platforms and hotels necessarily but, in this instance, between Airbnb, Booking Holdings, Expedia/Vrbo, TripAdvisor, and others. Google, which is in the initial phases of becoming a short-term rental platform, may also find itself subject to toeing the regulatory line.
