Airbnb $ABNB +3.51% announced Wednesday it is adding thousands of boutique and independent hotels, car rentals, grocery delivery, airport pickups, and luggage storage to its app, expanding well beyond its origins as a home-rental marketplace.

The hotel listings, which exclude large chains, will be available in 20 cities including New York, Paris, London, Madrid, Rome, and Singapore, with more locations to follow. Guests who book a featured hotel will receive up to 15% credit toward a future Airbnb home stay, and a price-match guarantee will provide the difference as Airbnb credit if a lower rate is found elsewhere, the company said.

New services include grocery delivery through a partnership with Instacart in more than 25 U.S. cities, car rentals with a 20% credit toward a future stay on first use, airport pickups through Welcome Pickups in more than 160 cities worldwide, and luggage storage through Bounce at more than 15,000 locations across 175 cities. Car rental partner names have not yet been announced, according to Barron's.

"Travel shouldn't just be convenient. It should be meaningful," co-founder and CEO Brian Chesky said in a statement. "The best trips help you explore, learn, and come home a little different than when you left."
