We stayed at Su's for a long weekend in Vienna. The place is wonderful, everything you need is there , it's silent, very clean and you get easily to the city centre or wherever you want to go in Vienna. Directly next to the appartement is a big park for relaxing, running or going out in the evening. Supermarket is at the same corner. Su was very responsive, welcomed us personally and gave us some good hints for the weekend. We can definitely recommend this place :-)
