I recommend this place for:
Best location possible
Full kitchen with washer and dryer
Roomy
Natural light
Excellent hosts.
only caveat could be:
if you come in July like we did and have to open the windows (because there is no AC) might be a little noisy. Is not terrible because it is not on a busy street, but I could easily loose my sleep. I asume that it only gets hot at night like 15 days per year in Vienna, so this would not be a problem most of the time.
