Overall, a solid hotel. There service seems friendly, the bed is comfy, and the room had ample space. Wifi is solid as well and you get tokens for a kolsch/non-boozy drink. It's just a short walk to the Heumarkt tram stop, but somewhat of a far walk from some of the restaurants we enjoyed near Friesenplatz.
That said, we didn't have any hot water one of the evenings we were there and the toilet paper is easily the worst I've had the misfortune of using. The tap water also smelled vaguely sulfuric, but not enough to cause concern.
We'd still probably stay there again if we planned on using public transit more.
