Coco has a good taste in design for her apartment. Her house is filled with her artwork. This makes the stay memorable.
The place is located in a nice neigbourhood, very close to the heart of the city. All that Vienna has to offer is easily accessible on foot. The city is full of imperial buildings and many museums (ranging from classic to modern contemperary Art)
For places a little further away (like the palace of Empress Sisi, Schönbrunn) you can take the free city bikes (subscribe while you're home for easy access).
I highly recommend Coco's apartment for you stay in this unexpected divers city.
