Saw other customers complaining loudly at the rental company.

No upselling, but the car given was too small. I booked a Renault but got a Kia hybrid, not sure what model. With 5 people and 5 suitcases, it couldn't fit anything else. Considered getting a bigger car, but the price doubled, so I decided against it. Spain really requires small cars; navigating old town streets and even regular parking lots is a test of driving skills and judgment. Another issue was that the trunk couldn't lock, not sure why. Remember to send the address when picking up the car; just head to the car rental parking lot. There was a traffic ticket and toll fee from Portugal; not sure how much of the deposit will be refunded.

There was no queue when picking up the car and the paperwork didn't take long. The staff assisting us was polite. The company might include some insurance in the contract by default, so if you sign without looking carefully, you may end up paying more when returning the car.

Tried to charge me for fuel but had to show them it was Full to Full. Then gave me a van instead of a car and said they didnt have anything else. Was asked to come back next day and picked up a better car. Hassle but worth it in the end

Pick up time was way too long. Long cue, lack of personnel.
