Vladen & Anna were quite responsive and courteous, responding to queries quickly. Their flat was very nice and cosy...just right for 4 people. There cannot be a better location in Vienna; the apartment is almost just across the road to the Hofburg Palaca and the Museums Quarter and at 15 walking distance to most places of interest in Vienna.
Our entry and exit from the flat was very smooth. Vladan's colleague was there to receive us when we arrived and explained the important things to us.
That flat is exactly as was described and as the photographs showed.
