Gerd was a great host - very friendly, welcoming and flexible. I enjoyed staying at his place, which is in walking distance to the city center and in close proximity to a number of tram stations. Three well stocked supermarkets and a bakery are around the corner from the flat. The wifi worked seamlessly. The apartment looks exactly like in the pictures Gerd posted on airbnb. It's a simple but roomy and squeaky clean flat in an old Viennese house. A big plus for me: it was super quiet at night! I think it was excellent value for money and I would stay there again. Thumbs up!
