I think that this is a baby gecko, although baby iguanas are green also, and I must confess that I cannot tell the difference.
We like geckos because they are cute and they eat insects. At night they will perch upside down on the ceiling of the patio of our condo. They can make a chirping sound louder than a bird.
I took this photo on the very short path from our condo to the beach in Playa Langosta.
[Later note: If you click on the comments, you will read that this is a baby iguana.]
