They miscalculated the price on the spot

Poor attitude, unclear explanations, misleading information

Enterprise is very convenient as their station is the first one right outside Terminal 2. I rented a Passat but they upgraded me to a fairly new Mercedes. Returning the car was also easy at Terminal 1, as there are service desks at both terminals. You can take the elevator to the departure level after returning the car. The only downside is that the staff speak English too quickly and keep trying to sell insurance and GPS rentals, even though the cars are usually equipped with it. Renting a car is quite necessary when traveling in Germany.

Good

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.
