Katja was a fantastic host who went out of the way to provide support. The place has excellent amenities, and is extremely comfortable and peaceful. It feels much larger than the pictures portray, and the extended balcony on the ground floor gives it even more space. The in-house coffee facilities were much appreciated! The apartment is really close to markets and transport connections; though the neighbourhood itself is demographically diverse to the extent that it does not render the experience of being a classic Viennese district. Overall, I would highly recommend the place.
