I usually stay overnight or weeekends when I go. There are a few MP's where they will do FS for 400-600 pesos ($22 to $33). I prefer Stoya (

Unfortunately they all seem to close pretty early though (around 8 PM) and getting a girl to come back to the room can be hard at least for me since I dont have any spanish skills. I do have one there though that I met at a MP and she speaks very good english and comes to my room after hours. Sadly the service is still pretty much the same methodical service you get at the MP although the bed is larger and more comfortable for my fat ass.
There are a couple of clubs but they were too crowded and overpriced for me. A friend brought a decent looking girl back to the room from the Joker for around 2500 pesos ($140) for 3 hrs. He said he had a good time. The one I saw there and wanted did not do outcall and I passed on the girl they wanted me to take instead.
I learned from experience that Sunday is not the time to be there. It is very dead I guess they are all at church and even the MP's are only open for a couple of hours.
I am thinking on going this weekend. Would be happy to check out your young lady friend and let you know if she is the real deal if she is there
