Pros: nice car, reasonable price. convenient pick up outside train station in Salzburg. the Austria highway pass was on the vehicle and we didn't need to pay extra for this. Price quoted was in dollars - did not have to deal with conversion.
Cons: Drop off instructions were poor. We picked up the vehicle in Salzburg, and dropped off in Vienna. The address for the GPS was the location of the office inside the train station. I asked the person whom we picked up from if the GPS address would get us where we needed to go, and they said yes. There were no additional instruction (take car into parking garage, second level down, and then follow signs for where to drop car), and the parking garage had no external signs to indicate this was a rental car drop off location. The parking garage also had cones and ropes blocking off the entrance. We could not figure how to drop it off at night and had to come back the next day.
