Overall not recommend this place. The price is lower than your average room in Vienna, but what you get in exchange is not worth for what you are saving.
The room was dirty, the towels were not properly washed, and the light was very bad.
Communication also felt like talking to a robot. Lots of automated messages, didnt feel like I was talking to a person.
The good thing is the location - Close to the U6 metro, so you can get around easily no matter where you want to visit.
