Cold applying to language schools in Spain

Hello everyone.

I was trying to see if this was already asked, but couldn't find anything, but if it was already asked (and if I didn't look hard enough), please disregard.

I have decided to apply to private academies instead of renewing in the NALCAP program. Someone I met recommended a language academy in Valencia, but told me to visit the academy and drop off my CV instead sof emailing it.

What would be the best way to go about this? Visit the academy and drop off the CV? Or contact them first and schedule a visit?
