My80-year old dad and I LOVED Katharina! She was very knowledgeable and obviously loves Vienna. She was one of the brightest highlights of our entire three-week European vacation. We were frankly a bit tired of the same old tours day after day, but we will never forget our two hour off the beaten path tour with her. she has funny stories and memorable remarks. I would highly recommend her.
