This is an amazing hotel. It is extremely close to a lot of things around town, especially including a metro stop that will easily take you directly to the center of town. It's within an easy walking distance to the Prater entertainment area which is definitely worth going to.
At first, when I arrived, it was night time and I was kind of worried about the area but my fears ended up being unjustified as it just looks like a sketchy area and I never felt unsafe at all, even when I was walking from the hotel to the metro stop to go back to the airport at 3 am.
