thanks guys

I was in Lima for 5 nights in 2016. JW Marriot Mila Flores area. I had god luck with hornet and grindr. 6 men in 5 nights. 3 were free, 3 were paid (about $50). I did not get to explore much because i was on business. wished i had stayed a couple extra days.

I would go again. Have fun!
