Visiting friends in the ROMA/CONDESA for a few weeks and this was the closest gym to my airbnb,…read moredon't recommend it unless you don't mind rude/pervy staff (the trainers/manager had wandering eyes and gave me the heebie-jeebies) ,dirty premises and a chaotic floor, nobody picked up their weights, people were talking on their phones while sitting on the machines, that sort of thing.
For a few days it was ok if a bit expensive, not sure if there are better options around.
