I think that CAC is a great gym for working professionals in the area. I find the CAC team to be friendly, and the machines and equipment are reliable. My only constructive feedback would be that somehow opening up the stretching areas and maybe adding another area for TRX bands would be helpful. I also do wish this location was open on weekends - 215 First St. is a lovely location, but far enough away that it's a bit of a drag in the winter.
The front desk is friendly, music is nice and not too intrusive, and the instructors of classes are friendly. Locker rooms are generally well maintained, and there are always fresh towels. The gym seems well maintained as well- happy they resurfaced the floor in the classroom. Still wish there were more efficient hairdryers.
I visited CAC Tech Sq when First Street was closed. It was a nice club -- was more visually appealing as well in terms of color scheme and locker room.
