Well that depends where you want to go. Downtown Lisbon District, about 4 miles from Lisbon Airport (LIS-Humberto Delgado), can be a bit tricky to drive around. Make it easy on yourself by opting for something small, fuel-efficient, and simple to handle. That said, Lisbon District is a handy base from which to explore some of the bays around Portugal. If your escape is more about cruising down highways, then you may like something with a bit more comfort and extra legroom. What about an SUV or a full-size car?
