Vienna is a really lovely city and this appt was the perfect location to see it from! 5 train stations to Karlsplatz in one direction, 1 stop the other direction is the spectacular Schonbrunn palace (actually we walked, it was so close). Kemal and Maida (sorry if i have misspelled) were wonderful hosts. Very informative and helpful, even supplied a local prepaid phone for emergencies so we didn't have to use ours with international roaming charges. The apartment was immaculate, airy and spacious. As it is situated on the main road, you are aware of traffic noises but this is to be expected from any centrally located apartment and it was not intolerable by any means. Would highly recommend this apartment for your next trip to Vienna.
