Kurt and Sabine's apartment is short distance away from most places you would want to see in Vienna. The apartment is large, up-to-date with its furniture and spotless clean. The bathroom had Malin+Goetz products. It's on a third floor of a non-elevator building. This wasn't a problem for us at all. Kurt and Sabine promptly responded to all of our questions. We had to pick up the keys from a location 15 min walk away from the apartment. I'd definitely stay in their apartment again.
