Choosing Europecar for car rental in Germany was a great decision, and it turned out to be equally good in Portugal. I prefer avoiding complications, so I booked the basic insurance online and purchased full insurance on-site. If the car gets scratched in the parking lot, you don't have to worry since it's covered by the insurance. Returning the car was a bit tricky, as I had to circle around several times; the navigation was incorrect and I had to ask for directions. To find the return location, navigate to 'Arrival,' and you should see signs for 'Car Return,' or follow signs for 'rent-a-car.' Near the airport's arrival exit, there are fewer signs, so pay extra attention. If renting from an airport location, keep in mind that many lower-cost options might require a shuttle bus for pick-up.
