Sascha & Marina are excellent hosts, they always respond immediately to my questions in written or by phone.
The photos of the place are accurate and the location was perfect for us as we were looking for something close to Schonbrunn. You can walk around 12 minutes to get to the its garden entrance.
My husband and I were travelling with other couple and certainly I wouldn’t recommend this flat for 4 adults with the current setting since the sofa once open only can fit 1 adult and they gave us and additional portable bed that was to short for me (I am 1.75 mts). Be aware that you will need to open the windows for ventilation and to refresh the flat.
