The flat is as nice as per pictures, spacious, with comfortable bedroom and nice bathroom (bathtub not shower-cabin). Good taste really. The communication with Yaromyr has been very easy and prompt. The U4 metro is less than 10 minutes away and the Schonbrunn palace is 1.5km away, walkable.
The only thing is that is not in the centre proper of Vienna, so do not expect a shiny, fancy neighbour.
