Designers were also excited about the system. It enables product reviews to focus on the actual concepts and experiences of a design, rather than padding, colors and type choices. The DLS provides us with a shared understanding of our visual style, and streamlines contributions to a single system. This system also enables all of us to prototype and experiment with ideas in high fidelity faster and at a lower cost.
Due to the growth of international end-users, in early 2012, Airbnb opened offices in Paris, Milan, Barcelona, Copenhagen, Moscow, and São Paulo.[36] These openings were in addition to existing offices in San Francisco, London, Hamburg, and Berlin.[46] In September 2013, the company announced that it would establish its European headquarters in Dublin.[47][48] 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.[49][50]
In January 2018, a federal court ruled in favor of Airbnb in a lawsuit filed by Aimco involving its tenants illegally subletting their rented spaces on Airbnb. The court defended Airbnb under Section 230 of the Communications Decency Act which does not hold Internet based services liable for the actions of their users. Instead the tenants are believed to be held responsible for illegally subletting their spaces without attaining prior consent from their landlords.[154][155]
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.[9] Landlords or community associations may have restrictions on short-term sublets.
