Pretty good routes and plenty to choose from. Easy to access from the Metro (line 7 Villejuif). I wish it was just a bit cleaner. It's definitely a more worn out gym, but at least it serves its purpose. It's more of a bouldering gym, so don't get your hopes up if you want to do some sport climbing. There's also a sauna (co-ed), gym with treadmill, weights, area for streching. Oh and also a bar and some snacks if you get hungry.
