For the price, the hotel was great. No crazy amenities, but it felt clean and the internet worked well. The area is walkable to the Hbf and the city center. Nobody was at reception when I arrived, but they came right away when I called and were very kind and helpful (despite my poor German). The shower was broken, so I had to hold the spout the whole time by hand, and the carpet was coming up at the walls. Neither were end of the world problems for me.
