I use the water side facilities, but the gym looks well equipped. It's a 14m pool with room for 3 lanes. They've had a few problems with boilers and pumps and the changing rooms are small. The ambience is pleasant and the staff friendly and co-operative. I've only had fair dealing in the many years I've been a member. The big plus is that the owners and sisters are often on site and do care. It sounds like the opposite of 37 degrees.
I was just looking at that gym you mention, the only problem is they do not mention any charges on their site to join which is a bit crafty really. It looks great there, but what is the charges, thats what people want to know?
