Alejandro was exactly the kind  of guide I was looking for. He arrived promptly, even a few minutes early. He was so knowledgeable about everything. There wasn't a question I could ask that he didn't have an answer to or at least able to research for me. He know about all the animals, all the plans, from medicinal purposes to how they interact with the ecosystem. I even learned their scientific names, and some Spanish along the way. He was patient and allowed me to take my time on the tour. He catered the tour to my desires, and where I wanted to go. He's very easy to communicate with. I am very happy I chose Alejandra as my guide, and I will  definitely hire Alejandro for another tour next time I come to Costa Rica.
