Croisieurope, sailing the Guadalquivir

Any body sailed this route? Have done several river cruises with different companies, but not this one.

I'm interested to try, so any reviews would be all.

I am interested as well... was looking at this - and then decided to do Peru next year, so have a bit more time to do some research.

Hopefully someone will have done this, and can offer an opinion.
