We reserved our cars on 19. March and today (30. March) we went here to Avis with reservation confirmation and we have been waiting 2 hours and our cars were not ready. We claimed FULL REFOUND!
Office staff seems uninterested and does not even know where the closest gas station is (NB! It's around the corner...). Otherwise location is good if you stay in upper South Beach.
Worst Avis location in the country. I specifically reserved a Cadillac CTS and they gave me an Infiniti filled with beach sand. Plus wouldn't drop me off afterwards like corporate said they would
