Rent a car here back in april 2024. We got a free upgrade for the car . Thankyou so much for whoever did handling my booking. (I'm sorry i lost your card, that's why i can't mention you guys- but i'm pretty sure it was the morning shifts guys- 2 people infact, thankyou guys , we did have so much fun !! ) . We went there last minute , and still , best deal ever ! They spent time just for explaining the car. And making sure i'm perfectly comfortable with it. I did drop the car off at Geneva airport too, and yeah, fast and simple.. Sixt 's services is pretty awesome.
