I visited this place in July and had a very good time with (I think) Amanda. http://www.chicas7vips.com/person/rosa-2/
she was either a damn fine actress or very into it. Whatever, I got off big time. Quite easy to find, but you need to reach through the grille on the door to ring the bell that looks like a light switch. Some plaque on the wall with FST or something written on it, no Chicas 7 logo in sight... all a bit obscure, but don't be put off! I nearly walked off thinking they were closed but the mama let me in finally and presently a succession of delights were offered. Whatever the girl's name was I chose, she was a good pick. Great value at €60 for 30 min. DFK, OWO, rec rim, all my faves - basically a proper hot fucking. No sneaky extras, no stupid €20 drink, no bait and switch. I'm looking for my next opportunity to go to Spain! Can't vouch for any of the other girls, apart from their good looks, but I suggest you try over other places for similar money! Near Plaza de Espana metro.
