As this is becoming a car rental review, I'll point that if you travel to Spain NEVER rent from Goldcar. They are a scam, prices go as low as 15€/day but when you get to pickup the car they fight with you to take the insurance (the original insurance is only covers third party damage). Also they insist that you return the car with the gas tank empty the. They charge you 120€ to fill a small car. The cars are far from new, you have to wait long cues... Now I usually rent with sixt, they offer better price than Avis and Hertz and the cars and service are top notch. At least by the moment.
