Metro Centrale near Central Station, quite popular, mixed public, nothing special. Saturdays and Sundays a must for the milanesi is Royal Hammam at Lambrate, easy to reach with the metro, nice sauna with big pool, people with attitude and mostly part of a circle of friends, interesting however because is the only place where you can find escorts from Egypt or generally North Africa, usual rate is 50 euro, 99% top. I hope it was helpful
