I had a wonderful stay at Katinka’s place and would definitely stay here again, when in Vienna. The apartment is beautiful and even more spacious than it looks on the photos, located in a gorgeous Jugendstil building. The apartment has everything you need for a comfortable stay, even more. Although it is not in the city center, the 13th district is safe and lovely and you need only about 25 minutes to get to the city center. Schönbrunn, Klimt Villa, Lainzer Tiergarten are close by, reachable on foot. On the top of all, Katinka is a wonderful and helpful host. Highly recommended.
