Hello! I know the Hispaniola Spanish Language School in Santo Domingo, I don't know if it's a really good school, I never went
there, but I heard about that school, they said that it was a good school. Check out the site at : www.hispaniola.org/
And good luck!
Do you know of any schools in Puerto Plata? Most of the schools I have seen can charge upwards of $1000 a month. That seems a bit excessive. It doesnt even cost as much in the US.
