Firstly, the hybrid model I specifically chose for the higher price was not available at all, resulting in additional costs. Secondly, it was agreed during booking that adding an extra driver would be free of charge, but I was still charged for it. I plan to file a complaint for a refund on this matter. Picking up the car was fine since it was at the airport branch, but the return location was hard to find. The address simply stated 'airport,' which is too vague for such a large area. A properly marked return address would make things much easier—just adding it clearly and making it searchable via Google Maps for navigation would suffice. This kind of issue reflects poor coordination between the company and Europcar, making it seem like a middleman that doesn't have things fully streamlined.
