My wife and I travel extensively, and we must have participated in over 100 tours over the course of our married life. Having said that, Susanne's tour of Vienna ranks among our top five favorite tours. Susanne possesses all of the qualities that we would want in a guide. First of all, she is extremely knowledgeable about the history and culture of Vienna and provided detailed answers to all of our questions. Second, she presents information in an interesting, passionate, and well-organized manner. Third, she is an interesting, highly educated and worldly person who can speak about many topics outside of her area of expertise. Last but not least, she is a delightful person whose company my wife and I enjoyed greatly. Although we have never returned to the same travel destination, we would return to Vienna in order to take another tour with Susanne.
