I'll be in Barcelona this spring.  Can anyone tell me if sites like this are reasonably reliable and accurate?

I used a site like this when I was in Madrid 2 years ago and was pleasantly surprised when the escort that showed up was exactly the one in the pictures.

I've been to Barcelona and Madrid and in general found the sites reliable, particularly the ones that allow you to filter for independents. Be sure to check out the TER reviews - lots for Barcelona. I also have fond memories of a good brothel there, although I don't remember the name.
