Susanne's apartment is really great - nice furnishings, very spacious, 3 big bedrooms, a well equipped kitchen, wifi and the best thing is that the U (Metro) is on the doorstep - literally. 10 mins and you are in Stephensplatz. The only quirk is that the toilet is inside the front door and opposite the kitchen - not in the bathroom - but aside from that architectural annoyance, I would highly recommend the apartment. Susanne is very communicative and even met us 1 hour after check-in time 'closed' at 6pm, due to our flight only landing at this time.
