I was a member at Luxor when I lived in the city. Staff were OK but not too helpful or friendly. The facilities were OK but I have not found a gym here with really up to date equipment, I was completely spoiled in Scotland as the gyms I used there have the most up to date kit available. What I did like about them was they opened at 06:30 so I could go before work, it was on my tram route so no hassle. They also have a creche on some mornings during the week. Cancellation was no problem at the time my contract was up for renewal but that was the only time I could cancel without moving 40Km outside of Zurich. It has been 3 years since I went there so I don't know if it is different now.

I'm now a member of a gym near Affoltern a.A. so if anyone wants a recomendation for that area let me know.
