We booked a Volkwagen Golf for our trip but the car wasn’t available at the pickup. The agent tried to make us pay 38 chf more per day for a Mazda CX60 but we refused. We ended up getting the upgrade for Mazda CX60 for free. The pickup and drop of were easy and the agent was nice. Just don’t accept to pay more when your booked car is not available. They’ll end up giving the upgrade for free as it wasn’t customer’s fault. Recommended to us is e Sixt at Geneva Airport.
