We had a great stay at Hannes' apartment which is cool and breezy when it was over 30° outside! Everything was just as described and the location is just so perfect. Not only because it was close to our son's place, whom we came to visit, but the neighbourhood is easygoing and authentic, with nice places to go and eat/drink and just so close to the centre and everywhere else. We felt Viennese fir a few days. Our only regret is that we didn't get to meet Hannes in person, but making the necessary arrangements with him was easy and pleasant and efficient from beginning to end. He was very thoughtful and present, even at a distance. A highly recommandable place to stay in Vienna!
