Maybe check out Renon which is within fairly easy driving distance to Sanur,
One bit of advice I would give is to try to stay away from any place that has Balinese temples or those small yellow offering boxes inside the property boundary because despite what the owner may say to you before you sign a lease, there is a high probability that he & sometimes his wife, the kids & the dog will all be on your doorstep without notice doing their full moon ceremony once a month & then leave you to clean up after them.
Then there are all the other reasons to have ceremonies like before Galungan when the whole extended family may turn up, stay for hours & leave the place looking like bomb hit it, sacrificed chickens & all !!!....... In my experience, when it comes to performing their apparent ceremonial duties the Balinese have little concept of privacy as we know it, I say apparent ceremonial duties because occasionally they won't turn up at all & you are just left guessing.
