The gym facilities and it's equipment are good. It is usually clean and the courses are nice. But that is the only good thing about it.
The personel is terrible, they don't care about you and they spend most of their time chatting on the reception.
And be careful when you sign their contract. They won't let you leave even if you move to another city. Even if you move abroad they won't let you leave, which is my case. I am gone for germany for more then 3 months and they are still making me pay for it. Unbelivable really and honestly sad that they are so desperate to take money from their customer's pockets.
I would advise you to read carfully their contract and consider if there is no better alternative.
