This apartment was at a very convenient location! Metro station and cable car stop was just 100m. walking distance. Of course you can easily walk to the town center (stephansplatz). The apartment is very spacious, nice decorated, kitchen fully equiped to cook something, it has a WiFi connection and a cable TV. Therefore, i would recommend this flat for everyone who wants a good stay far enough from the city's crowd. Definitely a good choice for anyone visiting Vienna!
Thank you Christian for your apartment and for your help.
