Even without a character limit, it'd be hard to rave quite enough about what a great time I had with Gerardo and Anna. I did both my Nitrox and Advanced Open Water courses while experiencing the best of the local diving - Cozumel, Playa, and the cenotes, for a total of six dives over 3 days.
While the price point may be a little more than some of the larger local dive operations, it is absolutely worth it both for the individualized attention (great if you want to further your dive education) and the friendly atmosphere that Gerardo and Anna cultivate with their clients. I was traveling alone (and have very limited Spanish), so they enabled me to see a little bit of Playa that I couldn't have experienced on my own.
When I go back, I'll absolutely be diving with them again, and would recommend to anyone looking for a first-rate dive experience. The entire experience is tailored to what you want out of your dive experience, and Gerardo and Anna are wonderfully communicative and quick to respond and answer questions.
