I would suggest you to contact few agents via "Agents" section. They can recommend you quiet frond properties matching your specifications. However, you can also post your query in the "Wanted" section to let various agents and owners of the properties to contact you back directly.
If you have anything else to ask, please feel free to ask anytime!
Finding a peaceful place is more of a matter of luck, however I have a few friends and family who happen to live in fronds C and D and I have found both of them quite peaceful.
It would be best to get in touch with an agency who specialize in palm properties and talk to a few people who live there.
