Elke's flat was a brilliant place to stay while I attended a conference. It was really easy to reach by public transport - when I arrived I walked from the S7 train station (at Praterstern), and each morning used the U2 underground line (which is literally 1-2 minutes away) to reach the conference. The flat itself is spacious, with great roof top views, and unexpected vistas of a nearby church.
Unfortunately I didn't have time to cook but the kitchen looks well equipped.
I would definitely like to stay here again.
