Excellent service, got upgraded for free.
Beware for the return parking is not the same as the pick-up, it is across the street. I had to reverse out of the parking. Otherwise the car was almost new. I didn't sign-up for the full on insurance as it would have almost doubled the price and I like to live dangerously 😂. Return process was quick with no fuss, very nice personnel. I'll rent with sixt again.
