The service was very satisfactory, the staff was very friendly, and the pick-up and drop-off process was extremely convenient, located at the ground parking lot of Terminal 1 at the airport, less than 100 meters from the airport exit. Large companies provide excellent service and a quick, easy experience.

Quite satisfied, although my English isn't great.

I had already purchased additional insurance from a domestic insurance company on the ZuZuCar website, but even after clearly stating that I did not need additional insurance when picking up the car, the rental company still charged me 95.65 Euros for additional insurance from the credit card pre-authorization. Since I lost the contract and driver's license in the car when returning it, it's unlikely I can reclaim the charges. It's really disappointing that Avis, as a well-known international car rental company, resorts to defrauding customers for illicit gain.

The queue was extremely long. Although I had already paid the full rental amount on the platform, I was charged an additional 100 euros at the store, plus a 65-euro service tax for services that were never provided. It's been nearly a month and I still don't understand what happened. The staff's English is very poor, and the extra charges were taken without explanation. Absolutely a terrible experience!

Excellent experience, picking up the car at Madrid Airport was quick and convenient.
