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 vehicle was very new, there was no queue and we got the car directly.

Great. The reserved manual Golf model was unavailable, and we got a free upgrade to an automatic. The rental company's service attitude was good, the car was in great condition, and we were very satisfied. However, the return signs were not very conspicuous, making it easy to take the wrong route.

The service was great, and the car was pretty good. They even gave us a free upgrade.

The counter service was enthusiastic and the procedures were quickly completed, but we were not satisfied with the car pickup. We booked a German car, but we were told only Japanese cars were available unless we paid extra to upgrade to a German car. Really frustrating. We rented three cars, and one of the Audis had an alarm issue on the second day. It was difficult to contact the rental company by phone, but luckily we found an Audi service center that helped us resolve the issue. The rental company gave no prior warning and their phone line was always busy. We will definitely not choose this rental company again. Additionally, the rental location was easy to find, but the return location was extremely difficult to locate.
