Hannes is a great host and agreed to welcome us at his apartment although our flight arrived later than his available check in hours. The apartment is clean and very well located, near two metro stations and a short walk away from the center. Another highlight was the bicycles provided, that we used a lot since Vienna has a large network of bike paths across the city. There are nice cafes and restaurants in the neighborhood although is a very quite area. If only the apartment was slightly bigger... The main bed is upstairs and the ceiling is very low, same with the shower, but it should be fine unless you have mobility issues or claustrophobia. We'd definitely stay here again.
