This is a very nice Y. They are at the tail end of remodeling it, so it should be better than ever. They have a couple large pools, a huge room for aerobic classes, and a decent weight room. I've brought my daughter a few times to the daycare and they were very attentive and nice. This Y is also a member of the away Y program, so a membership here will get you into a bunch of other Y's.
The only downside to this Y compared to others is that you have to pay for the yoga and pilates classes and they require advanced registration. I like to drop-in on such classes.
