Italian escort scene is nothing short of pathetic. You are at the mercy of indipendent escorts. There's virtually no competition and no site like TER that keeps them honest (fun fact, LE DISONESTE = "the disonest" has recently become a fun euphemism in Italian to refer to sex workers). Best case scenario, you'll waste your time and money. Worst case, you may get yourself in trouble. If you are in the north, consider renting a car and heading to Switzerland or Austria
