This is a beautiful apartment in a great location. The space is exactly as pictured: roomy, bright, stylish. We enjoyed the balcony and working at the desk in that window.
There are a few "buts". The access code didn't work for us when we arrived, but it was sorted within the hour (we rang the number provided by Vienna Residence, but the person who resolved the issue responded via Airbnb - that might be the better way to contact them if the same happens to you). The apartment is generally very well equipped, but there is no freezer, and shampoo and shower gel weren't provided (but there's a shop right across the road). The apartment is really quiet with the windows closed, except for the air conditioning, which was noisy at times, gurgling and sloshing (but maybe it's just a temporary issue).
It was really easy to eat well without going far: Tian Bistro am Spittelberg was a highlight, and Erich, Ulrich, Cafe Namenlos, Nola, and Coffee and Friends (just around the corner) were all good.
Overall, we'd happily stay there again.
