Marlies and Dominik have a great apartment. It's very clean, stylishly decorated, and close to several streets filled with restaurants, bars, cafes, and interesting shops. It feels like you are staying in a real neighborhood instead of a touristy area. Getting to the sights downtown (1st district) is a moderate (a bit more than 20 minutes), though very fun walk, and there are some public transportation options that can make it even quicker. The apartment itself has everything you could ever need, and Marlies and Dominik have created a very detailed guide with tons of recommendations for things to do in the area. Overall this is a great place to stay in Vienna!
