Unfortunately we didn't meet Nadia, but her mother was a great host. Nadia’s mother was really, really nice, she recommend us and explained us the most important things to visit in the city.
The apartment is very nice, cosy and clean and looks exactly as described and pictured. From this area you have fast access to the city center .The place is super close to the U-Bahn. We had a great time staying in Nadia's apartment. We would highly recommend staying this apartment during your visit to Vienna!
