There are two aspects to this business, the pool, and the gym:
Pool: Lots of space, with plenty of lessons going on to keep everyone happy. Outdoor/indoor, kids' play pool, and a creche. We took our infant son to swimming lessons there from 4 months old, and our teacher was lovely. However, we took him out, immediately before he graduated to the 3-5 year old bracket, because, while that teacher was lovely with infants, she ruled with an iron fist and a loud voice with the old kids. That style simply wasn't for us.
Gym: Lots of equipment, plenty of treadmills, bikes, cross trainers, and a couple rowing machines. Seven TVs showing various channels in the cardio section. In the weights room, lots of mirrors, two TVs playing, generally, music videos. Lots of space and lots of weight equipment.
The staff for the centre floats back and forth between the gym and the pool, and they are all lovely. My wife and I bought year long memberships to the pool and gym each, but when my wife lost interest, they transferred the balance of her account onto mine, so that her subscription wouldn't be wasted. They also deferred my account when I went to America for a month.
