Not being located within Frankfurt Airport is very inconvenient. After calling the contact number provided, we realized it was in German, which we couldn't understand. We had to get help from the rental car customer service to reach the store. We waited for about 20 minutes to be picked up at P19. The service staff was very friendly, but the car provided was disappointing. We booked a Passat wagon, but they gave us a Renault Scenic. As someone who doesn't drive French cars back home, I was already skeptical. And my concerns were confirmed — the car was underpowered and very unstable at 130 km/h. It was also a manual, and being unfamiliar with the road conditions, driving it was exhausting. On the third day, we arrived in Munich and contacted the rental company to upgrade the vehicle. We found a Kia SUV at a nearby Munich Airport location. The new car had excellent power, a stable chassis, and many features, allowing us to complete the trip smoothly. However, there was a small incident when returning the Renault at the Munich Airport store. I realized I had left my sunglasses on the dashboard. When I went back to retrieve them, one of the staff had just driven the Renault out. I informed the reception, and they asked me to wait, saying the staff member would return soon. Half an hour later, the staff returned, but my sunglasses were missing. The staff member claimed to have never seen them. Without any evidence, I had no choice but to accept the loss. This incident taught me that not all Germans are highly trustworthy.
