I liked the location. The Hotel is a short walk from many nice places to visit.
I was upgraded to a residence which was nice and spacious but missing the normal things like coffee machine and coffee.
Many things that would be avialavle in a normal room were not provided.
When checking out the sustem and before setteling my final bell, I noticed that the charge was double the expected. It was a system mistake. My advice, always check your bill in this hotel.
Overall, I liked my stay in Vienna.
