We had an incredible expirience with Ana! It was the most exciting city tour in one day that we've ever expirienced! And we travel a lot! :) She is so dinamic, knowledgable, helpful and fun! It was wery important for us to find out more about city's history, and she was just amazing! I almost felt like Serbian :) We visited Zemun, Avala, beautifull Belgrade fortress, mounumental Temple of Saint Sava, Royal komplex, lovely Skadarlija, Partizan stadium... We enjoyed the tour! The time just slipped away. We will definitely come back next year!
I strongly recommed Ana as your city guide. You will love Belgrade for sure! ;)
