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.
Hosts provide prices and other details for their rental or event listings. Pricing is determined by the host, with recommendations from Airbnb. Hosts may be required to report income and pay income taxes on income received via Airbnb. In the US, homeowners who refinance their mortgages with some agencies are able to count income they earn from Airbnb rentals on their refinance loan applications.
