From some of the reviews I'm reading the San Luis sounds like a real dive. Is this true? Drug dealers and prostitutes outside of it? Also people have said that toilets are backing up and all kinds of other nasty things. The island photos look really pretty so I'm confused on what to think at this point. I'm a real naturist in terms of appreciating things "unspoiled" by humans, like the sea and the water life. In my research San Andre looks great because it's a protected UNESCO site for its water life and reefs but from what I'm reading the human factor is questionnable as it pertains to hotels and poverty on the island. Is this being exaggerated by others?
