It was easy to find the Sixt location. The pickup process took approximately 5 minutes, the dropoff was instant. The staff were very friendly. All documentation was sent via email. It was the first time I used the scanning machine that checks for car damages upon leaving and arrival, very fast and fair. Takes a couple of days to process the data. I unscrewed the radio antenna and put it in the door pocket (to avoid having it stolen), however the day after the dropoff I realised I had forgotten to put it back. Was afraid I would be charged for it but they must have found it... So all good.
