Nov.23, 2011. I would highly recommend Carlos Medina's private tour. Carlos is very professional, knowledgeable and engaging. His vehicle is comfortable and kept in great condition. Our group had a good range of ages and everyone agreed that it was a fantastic experience. Carlos knows how to please the tourists. He even took pictures of us and emailed them- what a thoughtful thing to do! I would absolutely recommend him when you are visiting Puerto Rico.
