Las Violetas is in the Red Zone 15-20 minutes outside the heart of the city. They charge a $5 to enter. Once inside the area you can choose from 10-12 clubs. The nice club I settled on there were maybe 5 girls there, it was early on a Wednesday night. Found a nice looking tall girl with great lags and ass after a few minutes of talk she suggested full service in the back room for $45 and agreed to $40. Another big brothel is located 35 minutes outside the center of town called El Charquito
