In arranging the rental, I was unaware that the office I was renting from was an off-airport location. Much confusion when I tried to get the car at the Charlotte airport, then had to take a taxi and pay ~$70 to go to where the car was. Giving an address of the location is good but it should also say "off airport". Also, the car's batter died during the rental, very inconvenient. The fob was reluctant to work, screen said batttery low. So I went to a battery place, replaced it and no improvement. The car had 50,000+ miles on it, and obviously had not been checked out prior to the rental. Wasted much time trying to fix the problems.
