Hi Bad -
You might try KC (Kathy Carpenter). She has a lovely separate villa up at Los Encantos. We should know --- we tried to buy it but couldn't come up with an acceptable financing plan at the time.
It's two bedrooms, but you might be able to work something out. A gently secluded place in walking distance of Mombo restaurant, private pool for the four villas there.
Try her website. Go to "lodging" then click "Los Encantos Villa del Sol"
