Marcus was a great host, who took care of everything. As we arrived pretty late, we didn't meet Marcus, but he timely provided sufficient details and tips, so that we didn't miss anything and had a great stay!
The flat is perfect, not only for a weekend, but for a longer stay as well. Everything was crispy clean, the flat is tastefully furnished and the house itself is charming.
The neighborhood is very quiet and clean, while at the same time offering everything you need: restaurants, bars, shops, parks. Is is very easy to reach the city center, there is nothing we missed. Although Marcus lives quite near, he didn't interfere with our privacy in any way. When in Vienna again, Marcus's flat would be the preferred accommodation.
