Friendly stuff, beautiful landscape but bad management.
1.Negative points:
Expensive transportation to the island (twice the normal price you will get in "La Bodeguita" pier in Cartagena.
The manager was controlling everything, e.g place where you will seat in the island, place where you will eat, timing, etc. Not relaxing at all.
The island is not private, they receive visitors every day.
There is not much to do inside the island; the place is tiny so you better have some books to read.
2. Positive:
Friendly stuff
Beautiful landscape
Delicious Food!
