I have traveled all around Costa Rica and stayed in all kinds of places. There is not a single place I have ever seen like Crystal Azul. Whether swimming in the infinity pool, drinking at the bar, eating the amazing food, or just hanging out with Zene and Henner, count on having an amazing time as well as being being blown away by the views, the service, the hospitality, and (once again because they are just so amazing) the views. The first time up the hill can be a little scary, if you are a timid driver Henner, or someone, can come and chauffeur you up the hill but once you are up there, the drive doesn't even become a factor anymore.
I had the pleasure to stay at Crystal Azul multiple times and even with all that time there I still cannot find quite the right words to express what a magical place it is. I am almost hesitant to rave quite so much about how wonderful this place is, Crystal Azul and the rest of Playa San Miguel, because right now it has almost no visitors which means a private beach to spend time at during the day but some things are just too good to keep you yourself.
Final word: If you are in the San Miguel area, THIS is the place to stay.
