Barbara and Martin are both very nice and friendly hosts. They gave us a great tip for a vegetarian restaurant Hollerei (I highly recommend). Nearby of the apartment are a lot of local, often international restaurants and pubs, which is great! The city center you can reach easily by public transport, all the bus-, tram- and subways stations are located very close to the apartment.
We have everything we needed in the apartment and more than that! It is a very cozy, clean, tastefully furnished and solved place. Thank you very much, Barbara, we enjoyed our stay in Vienna and would come to your apartment any time again!
