They were quick to help us get the car checked back in so we could make our flight.
The agent asked me for the "passport" for the car. I had no idea what this was or where it was located. I thought he was referring to the paperwork I'd signed in Paris which we'd misplaced. Only after he pulled the documentation from the glove box did I understand what this important paperwork was and where it was located. The agent in Paris never mentioned this paperwork to us when checking out the car.
Friendly service when picking up the car. No long lines or wait times - staffing was appropriate. Great value for the money: car was clean and ready. Drop-off was quick and painless; friendly staff. Will use SIXT again.
