This hotel does everything but the room itself right.
Great included breakfast, staff speaks english, close to the central station and walking distance to shopping district as well as Koelnmesse.
But the room had lots of small dents, and the shower was in great need of service (one of the cabinet doors were missing, nozzle didn't work properly and the ventilation shaft was completely open). Bathroom door had no lock. Also, there were only two power outlets in the main room, both placed awkwardly by the foot of the bed with no table close to them. If you stay here, make sure to bring long power cords!
Seen better for the price, but the location, breakfast and staff bring up the value.
