Had a wonderful half day walking tour of Vienna with Susanne. She was very knowledgeable of the city from its history and architecture to the current day culture of its people. We shared the development of the city and its people over the centuries to the modern day and a little Sacher Torte and coffee also !! Susanne is obviously an intelligent academic but with a sense of humour and has the great attribute of being sincerely interested in her tour party and their lives. At the end of the day we asked for a seafood restaurant recommendation…. Susanne directed us to one of the best restaurants we have experienced for a long time. Thanks , we highly recommend you.
