First and foremost, DO NOT RENT HERE IF YOU WANT TO WORK WITH HONEST PEOPLE.
I had to sign the document of the state of the car before even receiving the car keys or even seeing the car. Upon arriving I saw damages to the car that were not documented. After telling the people on site, I was assured it was updated in their system and it all was written. I took pictures anyway as I thought that was weird. When giving back the car, no one on site. The next day a huge amount of money was deducted of my account without any explanation or email telling me why. After contacting Goldcar, I still have no clue what 'extra damages' were done. Goldcar has been silent since, I am still waiting to receive a receipt with the costs of the reparations (which are not going to happen as I am sure they will do the same trick to the next renter). You have been warned, beware.
