Anyone fished Rio Frio in Spain before (Andalucia region)? Or know anyone who has?

I am looking for a guided day or two on an upcoming business trip to the Granada area. Information seems a little sketchy online but I will be reaching out to one guide service I located called "Flyfishing Adalucia". I have a day and a half free and wouldn't mind roping a few fish if it's not too much of an ordeal to line up.
