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.

The airport counter staff were extremely friendly. Even when I returned the car to the wrong location in the garage, they still efficiently helped me with the return process.

We had a nightmare experience that is still ongoing - it totally ruined our vacation. We twice had to change cars due to 1 faulty car and 1 Mitsubishi recall - costing us two days of vacation circling back to Germany to change. Then after the second vehicle switch, we were charged 950 Euros (the full deposit) without explanation (bar one email to us addressed to a wrong email address). After many phone calls, being on hold for long periods and promises of calls back from Enterprise, we discovered that Enterprise at Nuremburg Airport (where we changed the second car) had 'discovered' damage after we returned the vehicle. Originally when we arrived they had thoroughly checked the car and exchanged telling us everything was OK, there was no damage. They just charged us without a discussion. Now they told us to email our complaint and we have had no response since we contacted them on 11th July. We feel scammed.

This part went fine and smooth - we were happy with the booking process.
