Luxury real estate in Key Biscayne | Ana Prado Contti

Paradise minutes from downtown

Key Biscayne is an island village south of Miami, linked to the mainland by the Rickenbacker Causeway. Here, everyday life moves at a beach-village pace: bike paths, marinas, tennis and a community that chose the island as a lifestyle.

The island's beaches rank among Florida's most beautiful — from Crandon Park to Bill Baggs Cape Florida State Park, with its historic lighthouse. It is a setting that feels far from everything, minutes from the financial center.

The island's luxury market blends waterfront estates of rare scale — like 485 W Matheson Dr, President Nixon's former 'Winter White House' — with sophisticated condos facing the bay or the sea. Rarity and privacy set the prices.
