I LOVE San Juan and all of Puerto Rico. I used to visit there almost every winter while I was still working and have visited pretty much the entire island. El Morro is amazing and Old San Juan is great to wander around in with all the colorful buildings. Not far from Old San Juan are the main beach areas: Condado, Ocean Park, and Isla Verde. I used to stay in the more local neighborhood of Santurce, not far from the beaches, and loved it. San Juan is definitely a place you should return to for a longer stay. Thanks for sharing your visit!
