Last I heard San Juan is a very high crime area.
.
No worse than LA, I’m sure.
I have spend many weeks in Puerto Rico for both business and pleasure. I have never had an issue with crime whether staying in a hotel or renting an apartment in Old San Juan, Condando Beach, Carolina Beach, Ponce, Ricon, etc. Like any city, there are neighborhoods in PR where I would be unsafe, but I have no reason to go there anymore than I have to go to the South Side of Chicago, NE Washington DC, or Watts in LA.
The people of Puerto Rico are generally friendly and passionate, and despite the common perception, they are not all liberals.
