Pros: No one answered the phone when I called about 6 times during operating hours to confirm the reservation. I went to the office and it was open with no customers and he said that he couldn't answer because it was so busy.
All in all it was better than other rental companies I have used in Argentina. It was cheaper, although still expensive by other country's standards, but they did not make up some reason for me to pay more when I returned it like others have done. It is hard to find a good rental company here, so this one is mediocre but still better than others.
