It's the standard process for European car rental companies. The car I booked was not available, and the staff tried to suggest an upgrade. I declined, so they gave me a similar model!

Very good

Due to flight delays, we couldn’t pick up the car on time. After negotiating with the rental car customer service, they agreed to delay the pickup time. However, the rental company claimed that since we did not pick up the car on time, the originally booked spacious station wagon was taken by someone else. We were given a compact SUV, a Peugeot 2008, which had very limited luggage space and was quite cramped. They asked for over 300 euros to upgrade, but there were no other cars available. The return location was extremely hard to find. We circled around the train station several times and finally found it by exiting one parking lot and following the right direction. Then, the staff claimed the fuel was insufficient (short by 3 euros) and made us refuel before returning the car. Overall, we were very dissatisfied with the rental company.

Overall satisfied. The car had quite a few scratches, likely due to narrow roads in older parts of the city, which affected its appearance.

High cost performance, easy car rental, and good service.
