Great option if you want to stay close to the main train station.
With Christmas markets in full swing I was not able to secure a hotel reservation at my usual hotel to the south of the train station near the Cathedral. The north side of the train station is a bit gritter and I generally don't stay in hotels on that side, but Kommerzhotel had me rethinking that choice. I selected the Hommerzhotel based on location right outside the train station and price. The hotel looks like something from the 1970s on the outside, and the decor on the inside is basic German practical. That being said the rooms were clean, the beds were comfortable, and the staff were helpful and friendly.
The sauna was NOT in working order, even though it was still a listed amentity, and the radiator heat was a bit temperamental, but I was still overall very happy with my stay, and would consider staying here again.
