Picking up and dropping off the car at Frankfurt Airport is very convenient. There's a counter in the arrival hall where you can complete payment and then go to the underground parking level 1 to get the car. Returning the car was a bit tricky, however. The navigation led us to the lower levels (B2 and B3) of the parking lot. After driving around and exiting, we asked the security at the exit and found out that the entrance to the rental car parking area on B1 is near the parking exit via a small ramp. It would be great if the navigation could direct us to that ramp directly. When returning the car, three people inspected it thoroughly, showcasing German meticulousness. In contrast, in France, a single person glanced at it and said it was okay.

If you're landing at Terminal 2 of Frankfurt Airport, I highly recommend this rental company. It's extremely convenient; the office is the first one you see when exiting, and it's very close to the parking lot, making both pickup and drop-off very easy. The front desk and parking staff provide typical German service—very warm and friendly.

Rented a car in Germany and Switzerland. The Enterprise rental counter at the airport was fairly easy to find. There were no lines, so the process was quick. They didn't check any translated driving license documents, just used my domestic license to get the car. However, the initial cross-border fee was high. After showing the staff the QEEQ order details, they reduced the fee by a few dozen euros (the order mentioned a capped cross-border fee). The order indicated a daily cross-border fee of 5 euros plus local tax, but the counter staff charged the maximum amount, claiming they didn't know how many days we'd be crossing the border. Is this reasonable?
