This is a perfect way to keep up your Spanish comprehension. It's advanced, but not challenging to follow. If you are advanced, you won't have any problems with this podcast. At times the conversations can be dull, but there are definitely enough of them so you can always find an interesting topic to listen to. I don't know of any other podcast like this one, meant just as a listening/comprehension tool, as opposed to a "listen-and-repeat" "course". Marina's accent is beautiful! And I really love the fact that she corrects Ben throughout the episodes...it makes me feel better about the frequent mistakes I make, and of course, I learn something with each episode. For someone who is at an advanced level of Spanish comprehension, I strongly recommend this series as the best way to keep up on their Castillian without actually moving to Spain, or finding Spanish friends!
