Here is a place I can say I went to, didn't like, and don't plan on returning.
During the summer tons of Bulgarians flock to the Black Sea.
I didn't know they all went to the same place.
The beach was so mobbed that I could barely see the sand. The town is known for having some very nice old churches, however people were selling junk everywhere leading to a highly unpleasant experience.
Not my cup of tea (but otherwise a very beautiful place).
