Every detail feels tropical and sexy, from the undulating ceiling in the sprawling lobby to Perla, the signature shell-shape restaurant and architectural marvel. The property is an icon of tropical modernist architecture and fits the ideal of a chic Caribbean resort. Perhaps as a result, it's the center of social life in San Juan for travelers and locals (including politicians and celebrities). The open-air lobby is a hive of dancing, drinking, and socializing most nights of the week, though if you're looking for respite, head poolside for comfortable chaises, umbrellas, and a surprising amount of privacy. Though La Concha hums with activity, the luxurious rooms offer a good night's sleep, not to mention exceptional amenities and extraordinary views.
