My beautiful flat can be yours for a couple of days. I live in a castle like building in the 15th district of vienna. The flat i am living in was bought recently and is still brand new. It offers everything you need to have (fully equipped kitchen, washing machine .. ) and the very high walls make the place really spacious.
5 walking minutes from the flat you can catch the metro (u4/u6), so it's quite easy to get around. Castle Schönbrunn is within walking distance :).
