I've felt extremely welcome and really enjoyed my time in this apartment. For one thing, it's extremely quiet, as it's overlooking an inner courtyard, with the birds giving pleasant concerts in the mornings and evenings :) Although it's in a relatively quiet area, there are quite a number of shops at a walking distance. The Prater, a large green park is also very close. The city centre is a short ride away as well.
As a host, I couldn't recommend Hannelore enough. Before coming to Vienna, I had quite a number of questions about the flat, which she always promptly answered. During my stay, she dealt with any issues I had right on the spot. The communication was always uncomplicated, and also she made sure things were taken care of even when she was away. Above all, she has been friendly and kind beyond all my expectations. For me it felt like I was staying at a friend's place rather than someone I don't know.
All in all, one couldn't go wrong with choosing to stay here.
