Flying to San Juan; I was in cruise flight at 2;000 feet 10 nm from Plaza Carolina. Mid-morning local time ATC advised me of traffic at 12:00; 1/4 mile; 2;100 feet. Since I did not see the traffic I immediately started a precautionary descent. I again received the same advisory for traffic at 12:00; 1/4 mile and 2;100 feet. At this point I had descended about 50-100 feet when an Aero Commander passed about 100 feet directly above my aircraft in the opposite direction.
A light twin commercial carrier pilot approaching SJU reported a near miss at about 2;000 feet after descending in response to an ATC alert about approaching an approaching aircraft.
