However the facility was one of the worst maintained I've ever visited. 100% of the weights were thrown about wherever on the gym floor and no staff cleaned up or kept them organized. The bathroom urinals were horrifically filthy and unbearably smelly. Speaking of smell, it would appear that at least 90% of the clientele haven't discovered deodorant. Sensory filth overload, 10/10! Like all multi-level gyms the layout of equipment isn't the greatest, but they do have a lot of equipment. This is the only saving grace about this gym. Not recommended to go here, but you won't have better luck finding a better gym in Cologne anyway.
