My friend and I booked the tour on short notice and were accommodated. Yes, there was walking and stairs, but Dragana was gracious and worked around it with 2 seniors who tried. Dragana was amazing, shared her depth of knowledge, fun facts and background information. There were stops for refreshments and also lunch on our own. Our driver, Dragan, was friendly, hospitable and contributed to the tour's efficient and timely progress. We'll book another tour when we return in a few months. Highly recommended.
