The store in the center of Vienna is very convenient, with car pickup in the adjacent garage, but the garage staff can be hard to find. Once the car is picked up without issues, you can leave directly. Driving was limited to Austria with a provided highway ticket. Returning the car was near Salzburg train station, which required a bit of walking, but self-service return was supported. Overall, it was satisfactory. However, the cancellation of the credit card pre-authorization took a bit long.
