Went in the afternoon, and the staff at Sants station handled everything very quickly.

I asked if insurance was necessary, and after saying it wasn't, they didn't mention it again.

Big companies are more reliable. The staff speaks good English and provides warm service. They offer insurance but don't force it on you. Explanations are clear, and the deposit is refunded very quickly after returning the car.

Great service - we arrived later than anticipated but the desk was still open on arrival. Also, we left a mobile phone in the car when we dropped it back and the Avis/Budget representative (a Mexican chap) very kindly chased after us from the 5th floor of the car park to give the phone back. Would definitely recommend!

Very good and simple service

The rental company charge me at the desk extra fee for a full fuel tank. I don't know why because I booked fuel option full and pay in advance. So I pay for this option twice.
