We have stayed at both el Zafiro and BSV. Both were wonderful. It depends on what you are looking for. We never cook so we really don't need the kitchen and atrium at Beachside Villas. I think their prices are comparable. Actually last August, BSV was more than el Zafiro. However, I'm not sure when the original poster is traveling. el Zafiro is newly decorated. They are both PERFECT locations! Can't go wrong just being there looking at the gorgeous sea views.
