Very satisfied!

In case of an emergency, most employees at Germany's Enterprise do not speak English, especially at the accident center and return points. They do not explain car swaps or charges. Without a German-speaking friend, it is almost impossible to resolve issues.

It's fine.

Pretty good overall, but they were quite pushy with upselling. We kept saying we didn't need it. The Frankfurt counter was a bit further away from the others, had to walk a few extra steps.

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.
