The gym itself I would give five stars, generally very clean and tidy, it has air conditioning and water dispensers (very slow, takes five minutes to fill up a bottle) there are a good selection of machines and free weights allowing you to work on all muscle groups.
The changing rooms and showers are very dated and cold, I'd rate them rated 1 star but that's because I'm feeling generous. The floor is always disgusting and wet making it a slip hazard and difficult to get changed after your cold shower.
The swimming pool is okay but a lot of the time half of it is shut off from the public making what's left quite busy, they also have a sauna and steam room but are temperamental whether they work.
