The wait time while queuing for the car was very long, and the staff's efficiency needs improvement. We booked a BMW 2 Series, but they claimed it wasn't available and offered us a POLO instead, unless we paid extra for a different car. However, when we picked up the car, the BMW 2 Series was clearly parked next to the POLO, which felt deceptive. The car return location was also hard to find; we returned the car at Rome airport and drove around in circles before finally figuring it out with the help of airport staff. Overall, we will not rent from AVIS again.
