Is Verena,Bulgaria good for travelling?

Don't you mean Varna, Bulgaria ?

I think you mean Varna, a town on the north coast of the Black Sea. Although I went to Varna about 10 years ago, I can recommend it. It is a place well worth visiting. We visited the international dance and music festival, the Maritime museum, and the beaches were also good. Many other places around Varna are great, and they're all within reach. And it's quite cheap compared to Turkey or Greece.

Assuming you mean the Black Sea city of Varna -- thumbs up, it is awesome! You’ll find a fine mix of culture, entertainment, ancient history, unique architecture, summer party spirit with bars and dance clubs along the beach, great shopping, delicious food… You can always just lie on the beach to soak up some sun… Varna is called the Sea Capital of Bulgaria for a reason… Go for it!
