If the Gym at your Apartment is Free I would do both, on Alternate Days.
I worked out at Curves for a little over 3 years, lost all my weight there, and was Maintaining without too much difficulty. Then the only Curves near my house closed so I was forced to go to a "Regular" Gym (Anytime Fitness). I seem to be having more difficulty keeping the weight off, and I do not enjoy the Gym as much as I did Curves.
However I know that Curves isn't the "Right" fit for everyone, so you have to do what is Best for you. I really enjoyed the time while I was actually an Employee at Curves (Free Membership) and I also worked out at Anytime Fitness on 2 or 3 days a week.
Figure out what works best for You and then Go For It!!!
