The apartment is excellent! It is spacious with a lot of natural light coming through large windows. High ceilings create a feeling of freedom and space. The bedroom balcony faces a nice green park so you don't feel like you are in a big city. The appliances and tableware are impeccable. We were very happy staying there and didn't want to leave.
The location was ideal for experiencing Vienna - It was walking distance to the centre, major museums and sights. There are plenty of nice trendy cafes and restaurants nearby. Gerhard was a very friendly and helpful host who recommended us good places to eat and to visit. He was responsive and very easy to communicate with.
