Airbnb uses drip pricing; when customers search for lodging, Airbnb displays per-night prices that exclude its service fees and the total charges are not revealed until the customer selects an individual property. After a crackdown by the Australian Competition and Consumer Commission in October 2015, users of Airbnb's Australian web site now see the total price of a stay including all unavoidable charges at every stage of the booking process.
Due to the growth of international end-users, in early 2012, Airbnb opened offices in Paris, Milan, Barcelona, Copenhagen, Moscow, and São Paulo. These openings were in addition to existing offices in San Francisco, London, Hamburg, and Berlin. In September 2013, the company announced that it would establish its European headquarters in Dublin. Prior to the 2012 Summer Olympics, Airbnb acquired London-based rival CrashPadder, subsequently adding 6,000 international listings to its existing inventory. This acquisition made Airbnb the largest lodging website in the United Kingdom.

Guests can search for lodging using filters such as lodging type, dates, location, and price. Before booking, users must provide personal and payment information. Some hosts also require a scan of a government-issued identification before accepting a reservation. The company also provides travel guides, entitled "Neighborhoods", which provide details about staying in specific neighborhoods in various major cities.
