Not good experience at all

Good

The car rental location in Hamburg is a bit hard to find; it seems the GPS might be slightly off. However, following the airport signs makes it easier to locate. The staff was very nice and upgraded us to a Mercedes-Benz C-Class. During the trip, a stone hit the front windshield, causing a long crack. We immediately stopped by the Eu store in Oldenburg, where the staff wrote a proof that it wasn't our fault, and the issue was resolved smoothly in the end.

Limited car models, they tried to make do with a Golf. Had to pay extra.

Both pickup and drop-off were in the terminal parking lot, which was very convenient. The car also came with a GPS, which was a pleasant surprise.

Acceptable
