Silvia N is extremely knowledgeable of Venitian history. We would have liked to move more around the square or city as she gave us the history of Venice. The first 35 minutes were all while we were standing still in St. Mark's Square which was tough on our senior legs. We did mention this to her several times. Perhaps I should have customized our tour or taken a different one. However, there is no doubt that she knows Venice and its history.
