What a special place. We loved Sofia so much, we chose to stay an extra 2 days. We arrived, however, on the eve of a long holiday weekend and were told all the college kids in town headed to the beach in eastern Bulgaria. Otherwise, Sofia is known for it's youthful nightlife. Regardless, we enjoyed the communist architecture mixed with graceful frescos seemingly everywhere you looked. But, as is usually the case in Eastern Europe, the outskirts of town can be quite bleak. Stay in zentrum.
