I stayed here for a conference at Messe Wien and the location was perfect being less than 5 minutes walk to here and the metro. It's easy to get into city centre or you can have a leisurely walk if you prefer. The apartment was very clean and well equipped and Jutta answered my queries promptly. It was very hot in Vienna when I arrived so it was a bit warm inside the apartment but otherwise everything was great. There's also a great value pizza takeaway right next door or there's a nearby supermarket.
