When I first found this store, I was overwhelmed. This place holds so many treasures, you'll need several trips to look through everything.
Franky's is one of the most popular thrift/vintage stores in Puerto Rico, and likely only one of a few.
The proprietor provides a lot of his items as props for movies being filmed in PR—like the recent Rum Diaries movie.
If you like vintage, then you'll love shopping here. It's on the corner of San Francisco Street, right behind the little plaza as you enter Old San Juan.
