Wonderful apartment in an incredible location. Throughout our stay, we were able to walk to all of the major attractions of the city. The apartment's proximity to a gorgeous public park was an added bonus, and we made frequent use of the local amenities throughout our stay.
We were able to comfortable cook and dine in the apartment with no trouble. The beds were exceedingly comfy, and the living area was large enough for the six of us to relax and enjoy ourselves.
One word of advice: when we visited Vienna, the temperature was abnormally high (around 35 degrees Celsius). I am told the weather we experienced was not typical for the city, even during high summer. The apartment itself became quite warm, although not unbearably so.
Given the opportunity I would definitely return, and the apartment was a wonderful base for our visit to Vienna.
