Nice to hear that you like so many things about your gyms!
I have something to add to my list: the fact that the shower area includes 1-shower stalls besides the more open spaced showers on the wall. And the fact that there are so many toilets there is never a line up.
It's in an old building, on several floors, so there are a lot of "hidden" spots, where you can skip rope or stretch on the mat on your own or with a friend, with nobody staring.
