A truly good experience renting a car. The last time I rented a car was almost a decade ago and I didn't know how things work these days. First a car was selected online as well as additional services and insurance. Everything was checked and confirmed by the agent, who suggested additional services. We then got an upgrade of the car, which was scary at fist, because it was a small SUV instead of a limousine, but was actually a very good experience. So after signing the documents, showing the ID, Drivers licence and the credit card, I got the key to the car and a parking ticket and headed towards the parking house to pick it up. When returning the car, I left it in the same parking space (especially marked for Sixt cars), returned the key and the parking ticket to the agent. The whole experience was painless and pleasant. Can only recommend Sixt and Alfa Romeo 😊
