I have spent 3 days in Kyong’s bnb and the place is really closed to Vienna Central Station and short walking distance to tram station connecting to opera. It was worry free for late night concerts as the roads from tram station to the premise are safe. Kyong is a good host. I felt warmed welcomed by Kyong and his family. Everything was exceptional and I could not expect more. I would highly recommend this property to all who interested visiting Vienna!
