Everything is wonderful. The apartment (No. 11) is very clean and equipped, the location is excellent, close to the Metro Station (line U1). I liked the way of entering the apartment, the encrypted door.
Igor is always available to answer every question and help in every way, we are very grateful for his hospitality, especially the day when we had to leave the apartment, Igor gave us a place to leave our luggage (because our flight was later) .
We spent wonderful in Vienna and if we go again, surely our choice will be the same host, Igor.
