The feature will allow professionals to filter homes and apartments that Airbnb has deemed Business Travel Ready. To qualify for a BTR listing, as the company calls it, the dwelling must have a desk, Wi-Fi, self-check-in through a doorman or digital lock and various amenities you'd expect at a hotel, like free shampoo, a hairdryer and iron. According to Airbnb, 90 percent of its customers are vacationers.

U.S. business travel spending is expected to reach $296 billion by the end of this year and climb 5.2 percent next year, according to the Global Business Travel Association, a trade group.

There are now more than 250,000 companies using it, including Alphabet Inc., Domino's Pizza Inc. and Morgan Stanley. Get the full story at Bloomberg
