Let me fill you in guys...Having lived in Athens for 15 years before moving to the UK.
There are two main 'red light' districts in Athens,Fyllis street and Metaksourgeio.
Fyllis street has many brothels where you pay E20 for a blowjob/sex and some places offer anal.No GFE of course.Women are usually eastern european and you get all sizes,from decent looking young ladies to veterans.You have to shop around really.
Metaksourgeio is cheaper ,costing E10 a pop,women not majorly worse looking but the area is dodgier.
Street girls are around Athens in various places with the Nigerians having a strong presence, being again on the E20 level with blowjob/sex in the car or the street.E10 for blowjob only.Police are after them so you have to be careful.
Condom is used at these places for all activities,independent report may suggest otherwise but it is extremely risky behaviour.
Next level from those are the 'studios' where you get more of a GFE and better looking girls for E50 a pop.Facilities and discretion vastly better and OWO is the norm.You can usually negotiate a round 2 for another E25 maybe.
Escorts can be found from all shaped and sizes with Romanians and Eastern europeans being the majority.80-100 euros per hour/2 pops+hotel(20 euros usually) but the service is usually better.
You can get very pretty women for around 120-140/hour no rush-no fuss with OWO but we are talking models here.
Last,for those into it,there is a ladyboy lurking area near Syngrou avenue where they offer their services for around 50-80 euros,depending on their looks.
