The paperwork took an hour. Initially, they said there was no automatic transmission available, then they gave me a diesel Renault. The problem with this big car was that I couldn't drive it out of the parking lot, so I had to come back and exchange it. It was quite a hassle. Even though I had already bought full insurance, they still made me buy insurance. Since I don't understand Spanish, they said it was a deposit that would be refunded. I was with my child, so I signed it. Later, when I asked the rental company, they confirmed I already had full insurance. Just a reminder, do not sign if the amount doesn't match when you pick up the car!
