I loved Base when I was a member. So many things you'd find in a high end gym (sauna, cold towels, built in locks) for not that crazy of a price. And free classes, including a spin room, with your membership. The spin classes alone were enough for me because it was essentially the cost of a boutique spin studio, except it comes with a whole gym too.

I haven't been a member in 4 or 5 years just because I moved to a building with a gym and it's sufficient for me, but unless it changed in the past few years I'd absolutely recommend it.
