I've been to Wandsbek, Eppendorf and my main gym City. They all have the same look and feel but…read moredifferent building set-ups. I like the City location because it's small and you don't have to keep changing floors. At the same time, Eppendorf and Wandsbek have better and more selection of machines and feel less cramped. Eppendorf has the added benefit of having a climbing wall so if that's your thing, go here. I found that Eppendorf had the slowest staff. I've been going to the City location for some time now and their reception staff is actually the fastest I've experienced, meaning easier in and out at the reception. I complain about them being slow but Wandsbek were worse and Eppendorf the slowest and least helpful. Otherwise, this location as the others was clean and airy. Just as expensive as the other ones, with all the benefits and drawbacks this entails.
