I was there recently. I didn't partake, but as an old hobbier I can't help putting out the feelers to get a sense of the scene. Keep in mind, I'm talking about the street scene here. I'm sure there are lots of high class girls available, but when it comes to the street stuff....scarey was my impression. Lots of Africans, lots of trannies.
I took an overnight train in Italy and at the 2:00 a.m. stop, (Pisa), the train was boarded by girls and trannies looking for some quick action. The quality was terrible. I shut myself in the cabin like a scared little boy and waited til they were back on the platform before coming out for a look at some pretty harsh individuals.
