In Barcelona, that is a wonderul city, you have got a lot of options to have good time, from the classic clubs to massage parlos, escort agencies, independent escorts that advertise on platform and also, of course, girls in the street working close to Camp Nou and Bus station
As far as i am concerned, i have enjoyed several experiences with girls of this agency
www.pecadosvip.com/en like Arantxa (redhair girl very naughty) and Valentina, blonde one and i can say that you have good value for money (from 100€/30 min - 150€/hour) and twice i called, twice i get the girls in the picture and beautiful ones --- so it is a good option
