Nice gym. The equipment is great. However, I don't advise training there between 17.30 and 20h - way too overcrowded.
Equipments are good, shower room is okay, price-performance ratio is good(~20€ pro month). I also joined mcfit for two month, so it just my opinion, Compared to mcfit:
Pro: free co2 water, nicer staff, closer to Bahnhof
Con: equipments, cleanses of dressing room, unpleasantly crowded in peak hours.
Overall, I choose cleverest because of the atmosphere and co2 water; mcfit don't even have still water machine, drink water from restroom just seems not right for me. And I have some unpleasant experience about the staff in Mcfit.
Its a great overall gym. The Staff is polite and can always answer my questions. The gym itself is always clean and tidy. Everything is where it where it belongs, for example the weights are where they belong not laying somewhere on the floor, like in other gyms that I have been. The only negative thing is the parking situation, there are plenty of people that are not members of the Clever fit but still park there. The staff does not care about it, so I recommend getting there with the bus is the best way.
The music is not what I really like, but for the price, it's a nice gym. There're a lot of equipments and good professionals, who are there to help you if you need assistance.
Bad service, cannot recommend
It is 'alright'. I have been working out here for more than 2 years. If you avoid the 17-19:30 peak time you can workout in peace. When crowded it is stinky and unpleasant.
