Airbnb features a review system in which guests and hosts can rate each other after a stay. Hosts and guests are unable to see reviews until both have submitted a review or until the window to review has closed, a system which aims to improve accuracy and objectivity by removing fears that users will receive a negative review in retaliation if they write one. However, the truthfulness and impartiality of reviews may be adversely affected by concerns of future stays because prospective hosts may refuse to host a user who generally leaves negative reviews. In addition, the company's policy requires users to forego anonymity, which may also detract from users' willingness to leave negative reviews. These factors may damage the objectivity of the review system.[126][127][128][129]

Another unique thing about software is that, while it can be considered a product, it doesn’t really wear out and get replaced like traditional consumer products. Code and designs created years ago still exist in many places, even after the landscape of a company and its product have shifted significantly. This requires constant maintenance and upgrading.

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]

The European Union (EU) warned member states against banning sharing businesses like Airbnb and Uber, stating that outright bans should be used only as a last resort to attain public interest and that governments should instead implement more moderate regulations, which the sharing companies have had to navigate through.[157][158] The European Commission advocated the EU's guidelines on regulating sharing businesses companies and warned that they were pulling massive revenues generated estimated at around 28 billion Euros across Europe.[159]


In August 2017, Airbnb cancelled numerous bookings and closed accounts belonging to attendees of the white nationalist Unite the Right rally in Charlottesville, Virginia, citing its community standards user agreement to "accept people regardless of their race, religion, national origin, ethnicity, disability, sex, gender identity, sexual orientation, or age."[151]
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.
