I've been working out at gold's gym the last two years and I'm just really happy. Just the fact that's open 24 h from Monday to Friday it's a big plus. There's indoor's swimming pool, sauna, steam room and many other facilities.
It's fully equipped and there's free wifi as well. Trainers are helpful and friendly, even the front desk guys are quite cool!
I just wish they had a very nice cardio workout class, they are lacking of a good one.
