A corporate apartment isn't a place where business is conducted. Instead, it's the term used for "turnkey" apartments that are usually fully-furnished and rented on a temporary basis.
The naming of a corporate apartment comes from its usefulness to "corporate" professionals who may travel from one location to another quite frequently.
Beyond the corporate business professionals who gave the corporate apartment its name, there are a number of others who may benefit from renting a corporate apartment.
Because corporate apartments are rented under short term agreements and are turnkey, they're perfect for house hunters who either haven't found the "right place" yet or want to check out the neighborhood before signing a long-term lease. Additionally, a corporate apartment would make an excellent pied-à-terre.
As with any rental, there are some pros and cons to choosing a corporate apartment.
Corporate apartments are generally standard rental units that would appeal to a "corporate" professional. That doesn't mean that they're exclusive to business-minded renters. Anyone who desires a corporate apartment can find one.
They're listed on the same sites that other available rentals are. Most property owners will share more specific details of the leasing arrangements in the information section of the listing — like in the listing for the Ava High Line apartments in New York City pictured above.
