We arrived at the correct time to collect our car, the large tattooed man behind the desk couldn't find our booking and tried to rent us a car for over 10 times the sum we had already paid one for. They were most unhelpful then we were then asked to leave.
We had to get a taxi (over €100) after we reached our destination we were told they had found the car and if we didn't return they would "fine" us €50 for a no show.
Very poor, leaving us without a vehicle due to their administrative error and no effort to put things right.
We had to get another taxi to take us back to the airport at the end of our stay.
MY ADVICE IS KEEP CLEAR OF GOLDCAR unless you want to risk being stranded at the airport.
