Absolutely outstanding on every level imaginable. TL/DR: We recommend Nikolina with the greatest possible enthusiasm! Nikolina has an encyclopedic knowledge of Dubrovnik and its history, and our 2.5 our walking tour was a perfect way to see this magical city and learn about the myriad factors and cultures that influenced its origin, construction, evolution, and history. A note for Game of Thrones fans (which we are not): Nikolina also does tours with GOT "flavor" to them -- she pointed out a few key sites to us, but that was not the focus of our tour. Mostly, she was thoughtful, kind, funny, brilliant, and personable. Sounds crazy to say this, and I am not one pronate to exaggeration...but it's difficult to imagine that there could be anyone better. We recommend her with the greatest possible enthusiasm!
