So first the positive, the staff is friendly, there are always machines open, the place is always reasonably clean, and it's cheap!
I love the 24 hour cardio and Weight machine rooms, it really gives me the extra schedule flexibility I need. I don't know what it's like at say, 4am, but if I need to get a little workout in and it's past 11, it really helps.
The only downside of course is that the freeweight room and locker rooms close, although a ymca locker room at 3am would probably be a really bad idea anyways. Oh god, now that I think about it, yeah, definitely keep that closed.
And the pool is really small.
