At the end of your rental, you should return the car in the same area than where you took it, meaning within a radius of 500 metres / 5 minutes by foot. If you collected it in a private parking, you simply have to return it at the same place. It’s best to see in advance with the owner what are the accepted areas.
A compensation fee of €100 will be applied if you return the car further than the accepted 500m/5 minutes on foot without the owner's agreement.
You don't need to pay to for the car parking when returning the car, but please note you must return it in an authorized location. In case of bad parking followed by a ticket, it will be your responsibility.
