We arrived late in the evening, but Wilfried was very friendly and a professinal host when we arrived. After a few days we had to change appartment because of a mix-up, but we where completly fine with it. I would not recommend the "City View" appartment if you are depended of more than 1 good bed, but the view over Wien was fantastic, and the appartment was well equipped with everything you need and more. I would definetly come back to Vienna Sky Flats another time.
