Airbnb(AIR B & B) A lodging reservation Web site from Airbnb, Inc., San Francisco, CA (www.airbnb.com) that lets property owners list their spare room, apartment or home in thousands of cities worldwide. Founded in 2008, as of 2016, Airbnb had more than two million listings worldwide. Its distinguishing feature is that the host is reviewed by the guests, and the guests are reviewed by the host. Payment is made to Airbnb, which forwards the funds to the host after the guest arrives and everything is as advertised.
The name was originally Airbed & Breakfast when one of the founders rented a room in his apartment with an airbed to accommodate the guests.
