Wait until you find out about the "Gremlins" on the dinning room...
There are a few horror stories that are not real, I can say:
"I now Puertoricans can be difficult sometimes"
but this mostly depends on what you are looking most of the time,
if you are looking for something to be bad you will find it.
My guess you will have no trouble with puertoricans as the situation is at the moment in Puerto Rico no many people will be crusing next year...
