Parts of Puerto Rico were really beautiful, and most of the people we met were really friendly. I really wished I could speak Spanish, because even though quite a lot of people spoke English, I'm sure it would have been a better experience if I could speak their language.
The highlight of the trip would have to be Culebrita. It was nice chilling on an island with less than 15 other people around.
Quick Tips:
If you want to relax and stay away from Spring Breakers and cruise passengers from the U.S., you should probably avoid San Juan in general. It's nice to stay there for a few days but during peak seasons, the place is packed with people getting off the cruises (thousands of people!).
I heard the west coast is nice but we went to the east coast. Culebra is a small island, and there isn't a lot to do in terms of shopping, nightlife, food, etc., but if you want to enjoy the beautiful beaches, etc., this is a great place to go.
Best Way To Get Around:
We took cabs quite a lot--from Isla Verde to Old San Juan, Isla Verde to Fajardo, and Fajardo to Old San Juan. Within Old San Juan, you can walk from place to place.
We nearly took a bus to this market, but we didn't want to waste time, so we took a cab instead.
