What really won me over about renting from Sixt was how friendly and helpful all of the employees were, as well as how easy the pick-up and drop-off process were. My flight arrived late, so I did call to make sure the shuttle was coming, but I did not have to wait long (maybe 5 minutes from the time I called). Picking up the car involved minimal paperwork/fuss, and the return was even easier. I would absolutely rent from Sixt again.
