Could not have asked for better living accommodations unless I stayed at the Hofburg itself.
The apartment was more spacious than I'd anticipated from the pictures, which was a pleasant surprise. I loved the high ceilings, and the clever use of space. The air flowed well, and I could keep windows open throughout at night, as the bedroom faced a quiet inner courtyard.
Pretty much everything you'd need to live like a local is in that apartment. I despaired a little at first over the lack of a microwave, but later figured out the oven had a microwave system in it.
So there was nothing lacking.
The location is superb, quick and easy to get to pretty much anywhere you want in town with a tram, bus or subway.
And for late night bite to eat (or grocery shopping) there are several places just minutes away.
Should I return to Vienna some day (which I'm quite sure I will), Josef's apartment would be the first place I'd check for availability!
