They charge a large deposit and insurance fee on-site, and if you don't pay, they fine you.

It's acceptable

Terrible experience at picking up the car here. Just because I didn’t want to purchase their own insurance (because I had an insurance with a third company), they treated me in very rude manner. The guy seemed offended and started telling me that I was the only one doing such a thing and when I ask you to give me a piece of paper where he wrote all the conditions of the deposit I was paying he throw it to the bin in such a theatrical way saying that that paper was his (he should have studied drama instead of being a mediocre rental car assistance). Then he made me sign the contract when it said that the card did not have any scratches when I have not had seen the car and I politely asked to see the car first. He shouted at me saying that that was normal procedure. When I arrive to the car there were scratches so I had to make them come to the car and amend the contract by hand.

They obliged me to pay a EUR 1.200 deposit for a 2,5-days rental of a Fiat Panda, even though I had purchased the full coverage insurance package from AXA. Furthermore, if you intend to pay with a Greek credit card, don't choose this company, as its POS is connected to a bank account in Spain and transactions are likely to be rejected due to capital controls. Terrible behavior by the counter staff. Too long waiting time, 2 employees at the counter who were also delivering and receiving back the cars.

Le loueur a tenté de nous vendre une assurance complémentaire et nous a vendu un supplément. Flex soit disant pour rendre le véhicule avec un réservoir non plein et à l'arrivée ce n'était plus ça ; c'était une charge de fonctionnement ! Golden car n'est pas sérieux ni recommandable

Fonctionnement service OK
