@Arthur C. I wouldn't live in Trinidad because of the history of crime there as you mentioned, and my perception is that it hasn't gotten any better. This was confirmed when I took an uber pool through Trinidad last year, I saw what looked to be prostitutes on the street corner and when two young blond girls got in my shared uber I asked them how the neighborhood was improving and they told me they were just coming from their friend's place in Trinidad and that friend had just moved to Trinidad a week before and that she was robbed the night before. Thus confirming my perception.
Also, I am still suffering from PTSD from living in Columbia Heights in 2003 when it was really ghetto (it's still pretty ghetto today if I am being honest) and I had my house broken into and robbed, crackhead hookers turned tricks in my backyard, etc. So after all that drama, I proclaimed I would never live in a "transitional neighborhood" ever again.
