A good place to rest. Very quiet, despite it's central location. This is because all windows are facing the backyards/other window-fronts, neighbours were very quiet as well. Heating works very well, flat is clean and well equipped, good wifi, tastefully decorated. Apparently Anna &Vladan run an agency renting out over 30 other places in Vienna. I imagine they are equally well managed, so might try and stay in another one of theirs next time.
