We searched the planet to find 20 of the best by-the-sea retreats you can rent for less than $7,000 a week (eight days, seven nights).
On 1½ acres of coastal rain forest in Manuel Antonio, dramatic 20-foot glass walls and vaulted teak ceilings are enveloped in 360 degrees of native tropical foliage and wildlife. Inside, a cascading waterfall at the entrance streams along rock-hewn grooves through the house, ultimately spilling outside into the infinity pool. Indoor gardens and white furnishings add to the home's Zen-like feel. At night, 200 inset lights illuminate the villa's four glass-encased bedrooms, decorated with white headboards. The fifth bedroom and bath are located in a separate guesthouse.
