Dan was a superb host! He provided fresh milk in the fridge to go along with the coffee pods and tea. He also left a bottle of wine and chocolates. He responded immediately when we had a minor issue with the faucet. He offered great advice for site seeing and eating in the area. His English was very good and made our stay easier (even though we should have used more German).
Do not judge a book by the cover. While the outside of he building made us apprehensive at first, the apartment was much bigger and better than expected. He did an excellent job of refurbishing and decorating the place. There was some street noise if we left the window open but no noise from the surrounding apartments. There are secured doors to both the building and the apartment. It is a safe neighborhood despite the graffiti.
It was a convenient location with plenty of restaurants, bakeries, and stores nearby. It was one U-stop to Schonnbrun and just a few to get to the center of the city.
