I had a terrible experience at Valeria Ferrer just over a year ago. The madam indicated FK and OWO were available and no extra but, of course, when I got there the silly South American girl I met didn't offer those services. She didn't speak any English. And the madam didn't either, so clearly she had been just saying yes in reply and using Google Translate to write texts.
Reading through comments on here, unsurprisingly, Felinas is better.
My general advice is to learn the Spanish for basic services and check when booking and the extras. And, if you want, check with SP on arrival.
