In February 2015, Amsterdam implemented a cooperative effort with Airbnb that incorporated a tourist tax on rentals and Airbnb's agreement to ensure potential hosts are made aware of required rules and regulations. London passed an amendment to its housing legislation in March 2015 allowing short-term rentals of up to three months a year.
In November 2012, Airbnb acquired NabeWise, a city guide that aggregates curated information for specified locations. The acquisition shifted the company focus toward offering hyperlocal recommendations to travelers. That same month, Airbnb launched "Neighborhoods", a travel guide of 23 cities that provides in-depth information via collaborative filtering to help travelers choose a neighborhood in which to stay based on criteria such as public transportation, dining, peace & quiet, nightlife, tourist attractions, and shopping.
Some cities have restrictions on subletting for a short period of time. Airbnb has published a list of regulations and requirements for cities in the United States. In some cities, collection of a transient occupancy tax by Airbnb is required. In many cities, hosts must register with the government and obtain a permit or license. Landlords or community associations may have restrictions on short-term sublets.
