Excellent location. We thought it was a bit away from the heart of Vienna but it was actually in a really cool neighborhood and right next to a subway station. We had an issue with the hot water while we were there but Felix fixed it quickly and gave us a discount for the time we were without hot water, so we couldn't ask for more. The place is really big with all the amenities we needed for cooking. There were also welcome gifts of ice creams and beer. I would highly recommend staying here.
