This is a decent place in a little bit of a rundown neighborhood. The rooms and apartment are fine and were reasonably comfortable. There is plenty of vehicle noise at night, so be aware of that. The entrance is pitch dark, and it was cold and damp in there.
Note that the closest underground station is under construction and not open until January 2020, so you have to walk extra to get to the nearest open station.
I think the price was a little too high for what we expected and we could have found something about the same closer to the center of Vienna.
