You asked about a studio; BSV units are not studios, to my knowledge. (Edited to say that I see now that you said either a studio or 1 bedroom. La Vista and La Vista beach also have one bedrooms). La Vista is located on the other side of Simpson Bay from BSV; to me it's more convenient to restaurants and such. You could actually walk to many Simpson Bay bars and restaurants if you chose to. BSV units are larger, and the beach there is better than the beach at LVB. I would still choose LVB over BSV because of the location.
