We had a wonderful tour of Kutna Hora and Sedlec with Olena. She was extremely knowledgeable and told us many facts about the places we were seeing and the history of the area. She was extremely kind and personable, a delight to be with. I had been ill the day before our tour, and because of this was not able to walk as far or as fast as I normally would. Olena was so kind and modified our tour to fit our needs. We still saw the things that we hoped to see and took a gentle pace. When we travel to foreign places now, we prefer to find private tours with experienced guides. For a little bit more money, it is so much more relaxed and customized. I give my highest recommendation to Olena. My experience with the Tours by Locals company has been excellent as well.
