Child-Friendly Villas

Hi all, we've got two young (5) children and we're looking for a holiday VILLA in the Portugal/Spain neck of the woods - key requirement is a villa with a pool, where the pool is SECURELY fenced off to keep the little darlings out of harms way...
Does anyone know of any villas/companies that might have what we want???
Thanks very much.
