Been to both Flores and Miramar. Got sick both times in El Salv (only once at Flores) so prolly not the best dude for providing advice as i freaking hate that place! Surf wise both are good. Stayed at a place in Miramar that changed owners - surf tours nica. It is right on the reef break. Loved it. 3 surf spots right out front with several more avaiable by boat and/or jeep. There are several places between Miramar and Sandino plus you might want to check out Transito to the south. No frills but comfortable. Windy! You surf till wind goes onshore then it drinky time!
