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.

I booked a Volkswagen but ended up with an Opel after some hassle. The car's built-in GPS was very useful. Germany is really great for road trips; driving at 180 km/h felt effortless.

The service is quite good, and the young guy was very enthusiastic. They upgraded me to a better car for free when the model I reserved wasn't available.

The experience was average. The only thing that exceeded my expectations was the free upgrade to an SUV due to the unavailability of the reserved model. I was first asked to change the return location, and then told that the bumper had scratches upon return. However, I had been very cautious and did not have any collisions. Thankfully, I had supplemental insurance.

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.
