We loved this apartment and our stay in Vienna. My mom, sister, niece and I stayed for a three night visit, and it fit our needs perfectly. There are comfortable communal spaces to relax and private areas to work and sleep. We were happy to live in the classic Altbau style and enjoy the view from the balcony.
The neighborhood itself is interesting to explore, but it's not far to walk to the more popular Viennese sights.
If coming by car, there's a parking garage a block away that charges just 10€/day (Afrikanergasse) (and another a couple blocks away at 6€/day).
A couple issues were quickly sorted with quick communication from the host's team.
Thank you!
