Satisfactory

The staff’s English was easy to understand and he was very polite. Even though the fuel was a bit low on return, he didn't mind. After refueling, we drove for a while. Time was tight and the Frankfurt airport area is quite confusing, so we didn’t look for another gas station nearby.

The rental spot was quite small and hard to find. After arriving at Terminal 1, you need to take an elevator to the car rental area. The GOLF I initially wanted to rent wasn’t available, so they gave me a Renault instead, which was relatively new. The rental process went smoothly; they just checked my translated driver's license. Returning the car was equally hassle-free, even though I was an hour late, they didn't mind, and I just handed over the car without any issues. Also, when renting the car, the staff might try to sell you full insurance, but don’t worry about it as the QEEQ confirmation clearly showed I already bought full insurance, so no need to purchase it again. I can recommend buying full insurance directly from QEEQ; it's not expensive. Fuel prices are high in Europe, and the car I rented was diesel, costing over 30 Euros for half a tank.
