All in all, a good rental.

The car rental service was good, but the instructions were unclear. After landing, the car we needed wasn't available in our terminal. We had to either pay more or go to another terminal. The car options (CRV Hybrid or upgraded to Tiguan) weren't different at all. They said we could just go to the parking lot, but after reaching the other terminal, we still had to handle things at the car rental center and not at the parking lot service center. This caused us to run around the airport several times. In the end, we got the Tiguan without paying extra. Online, both cars are listed as the same, and the hybrid is more fuel-efficient.

The counter staff upgraded my car without my consent, doubling the rental cost. Extremely frustrating.

Please note that Barcelona airport has two terminals. Make sure to choose the correct one when booking, as they are not well connected.

1. Never trust after-hours car return arrangements. Europecar in Barcelona is extremely bad. More than 20 days after returning a car, they charged extra, claiming the air compressor was damaged. This is outrageous! How can internal damage after such a long time be blamed on the previous renter? Another car had scratches when picked up, which I reported and photographed. Still, I was charged for repairs. 2. QEEQ is powerless in disputes. Despite providing photos, evidence, and reasons, there is no result from QEEQ. All I got was to wait patiently. After more than a month, there's no progress. I decided to use insurance for the compensation. 3. Always get full insurance. Without it, European car rental companies will find excuses, and QEEQ is useless. There's no way to recover your losses.

A too long of a process to get the car keys. I wish the staff was more informative as far as what is needed if traveling thru different countries, tolls, etc.
