Im very happy with the gym and locker room pool. People share lanes when I swim. On occasion I have to wait for a particular machine but there are plenty of other weights or machines to use in the meantime so its not something to complain or causes stars to be taken away.

Been coming here for years. Never had any issues. Staff is friendly and helpful when need be. Equipment is usually in decent shape and organized. Locker rooms are clean to cleanish. Perfect for a no fuss gym.
