We had a fantastic stay at Christian's and Jana's place! It's a very spacious apartment very central in Vienna. There is a big living room which offers enough space to relax after a long day in the city. We have been able to walk all distances in the center to discover the city. It's quiet and has restaurants nearby which made the stay perfect for the 4 of us. We can recommend the breakfast at Café Nuss - it's really good. Christian and Jana are great hosts, they have been really quick in communicating with us and where very thoughtful in leaving a little breakfast for us in the apartment.
