Karl's place has everything you would need in an AirBnb apartment. It is located near lots of commerce, many places to grab a quick bite and one of the best local restaurants with traditional Austrian food located nearby. You will have easy access to the train system to go into the center of town and also to the airport. The apartment is spacious , with lots of light and is located in a quiet building not far away from the shopping mall or places to walk along the Danube. Karl is a great host in constant contact and wanting to make your stay in Vienna the best it can be. Highly recommended.
