I went with my niece to Prague for three days before starting our river cruise. Because we had such a short amount of time to spend there, she arranged for Lenka to be our personal guide. She met us at our hotel the first day and gave us an extensive overview of the history and architecture of the country and Prague specifically. She definitely has an encyclopedic knowledge of Prague history. As a result we were able to absorb a greater depth and appreciation of what we were looking at and we never felt rushed. For me personally, hiring Lenka as our personal guide kept us from just wandering around wasting time and energy trying to find areas on our own and missing a great deal in the process. She always took us on the most convenient paths and included the most interesting "hidden" treasures and places to eat. Because she was so relaxed herself, it was easy to relax ourselves over lunch or an afternoon break to get to know her a bit also. She is a sweet lady who is very skilled and knowledgeable. She also takes the time to find out what limitations her clients may have and is always considerate of that. This is the first review I have ever given on an experience and I give Lenka rave reviews on every aspect of my time with her! She is just the best at what she does!
