Well that depends on where you’re going. Downtown Sofia, about 4 miles from Sofia Airport (SOF), can be a bit tricky to drive around. Keep things easy by choosing something small, fuel-efficient, and simple to handle. Keep in mind that Sofia is a popular base for exploring some of the snowfields around Bulgaria. If your vacation is more about cruising down long stretches of road, then you may prefer something with a bit more comfort and legroom. What about a full-size car or a standard SUV?
