This was one of the most enjoyable walking tours we have participated in. Dressed in his unique 14th century watchman's garb, David was every part the friendly and knowledgeable watchman, transporting us back to the early days of Prague. Tales of defenestrations, the plague and of public executions were weaved into the historical landmarks of the city as we wandered through it, assured always that we were in the safe hands of one of the city's night watchmen. Imaginative, entertaining and informative. Simply wonderful.
