Very bad, they overcharge

The staff's attitude was average

Pretty good, but their English isn't great, hard to understand.

The Avis counter staff at Barcelona airport said that I don't need to refuel the car, claiming that the company's fuel charges are the same as the gas stations. I used less than half a tank and didn't refuel before returning the car, but later I was charged for a full tank. This staff member seriously misled me about the fuel price and refueling rules, avoiding the important details, which is completely fraudulent.

I originally planned to rent a BMW 3 Series, but since it is considered a large car, I needed to have two credit cards. I only had one, so I had to switch to a smaller car. The staff was very friendly, and I ended up renting a Mercedes diesel car. The power was excellent. Thumbs up!
