Giving one star because there's no option for zero. The wait time was extremely long, over an hour and a half. The staff was very inefficient, and despite having three open counters, they were not proficient, so the line barely moved. Finally, they told me I couldn't rent the car without an international driver's license and asked me to negotiate with the rental website. I've rented cars in more than four countries and from the same company before without any problems. I don't want to waste any more words on this; I'll just consider it a donation to the Spanish road maintenance.
