Sofia is a beautiful city worth visiting for a long weekend. It offers an interesting combination of old glory dates with impressive, renovated buildings and monuments similar to central European capitals, tired buildings, reminders of the Soviet era and modern constructions. All of these in a welcome, pleasant atmosphere with many parks, nice restaurants and very interesting cafes.
