amazing walk and amazing concert! I was so lucky to listen to the music of Mozart and Shubert right in the heart of Vienna, the musicians were so passionate and the atmosphere of this small concert hall was just incredible! there was also a 10 min break to drink a glass of champagne or juice. before the concert I walked through the city, the audio guide was very informative and well prepared, so I would say that it was the best evening in Vienna, I highly recommend this tour to everyone
