Very interesting, informative bike tour with some socio-critical comments on the architecture, the history and present of Yugoslavia and Serbia. Our guide, Sarah, was very engaging, helpful and communicative. Her English communication skills are outstanding and she always made us feel like we were kings as customers. The flawless functioning of vintage bicycles, given the suboptimal quality of the road surface, could still be improved. We were completely satisfied with our experience and thanks to the chosen cycle route and Sarah's explanations, we were able to get to know Belgrade from a completely different, less touristy side.
