YMCA of Greater Dayton - West Carrollton Branch at 900 South Alex Road, West Carrollton, Ohio.

I've been a member for a couple of years now, and have been very happy with the experience.

PROS:
-The staff is super-friendly, and always helpful.
-The pool is a nice size, kept at a comfortable temperature.
-I seldom use the indoor basketball court, but it seems well-maintained.

CONS:
-Some of the equipment in the weight room could stand to be replaced. Also, it's a little cramped in toward one end of the room.
-Frequent pool closures due to swim meets and practices make it difficult to use the pool during swimming season.
