We arrived about 15 minutes before our designated pick up time.
The queue was short and moved quite swiftly. The clerk was very cordial and explained everything clearly and professionally.
As we made the rental reservation before reserving our accommodation, and realizing there is a Sixt office closer to our accommodation, we requested to be able to return the car at the closer office.
Not only was our request to return the car at the more convenient office was accepted, we were also allowed to return the car after the office had closed and without additional costs.
The car was exactly what we requested. It was clean and ran smoothly. I would have preferred the clutch release to be set a bit lower, but that's the only "fault" I could find.
We will definitely use Sixt services when we visit Dublin again.
