Katharina was a fantastic tour guide, my wife and I spent the day driving and walking through Vienna with her and enjoyed every minute. She is knowledgeable, enthusiastic, friendly, and accommodating. We had a fun day, learned a lot about Vienna. she knows all of the best sites, both famous and not, and knows the history of Vienna thoroughly. We strongly recommend her and will surely hire her again for our next visit.
