My wife and I stayed at Anna's place for a month on a working holiday. It was absolutely perfect! It's a great space and the location is ideal. You're 10 mins walk from Praterstern, which takes you to the airport. You're 1 minute from Tram #2, which takes you into the old town. And there is a supermarket on the opposite corner. There are 3-4 bakeries within 5-6 mins walk. The neighbours are all very friendly and we never heard them once inside. We had about 150 Mbps wifi, so more than sufficient for Zoom calls and Netflix. Anna responded very quickly the few times we reached out to her.
We can't recommend Anna's place highly enough and would be back in a flash.
