Cons: I specified the airport, but the app showed options at nearby locations as well without making that apparent. So we get off the plane and...no car. The experience got worse when the Avis attendant erroneously told me my car was at another location a half-mile away. Then after walking there and back for no car, she tried to pass it off as my fault for not knowing where my car was, ultimately at a mall location three miles away. Also, the car was old and smelled strongly like mildew.
