The Legacy of SeaStays at Castle Beach

Modern oceanfront luxury rooted in Miami Beach history

Where coastal serenity meets the energy of South Beach

Your Historic Mid Beach Sanctuary

SeaStays is the ultimate choice for travelers seeking to get the most out of their trip, whether visiting for business or leisure. Our premium collection of 65 beautifully decorated condominiums—featuring modern designs—is housed inside the legendary and Historic Castle-Beach Club Condominium, previously known as the iconic Castle Beach Hotel.

Perfected situated at 5445 Collins Ave in the scenic Mid Beach neighborhood of Miami Beach, FL, you are uniquely positioned away from the noise but remarkably close to the action. The world-famous South Beach is just 15 minutes away by car or via the free Miami Beach Trolley, which picks up right in front of the building. Perfect for seamless travel coordination, our resort property sits just 16 kilometers (28 minutes) from Miami International Airport (MIA) and 35 minutes from Fort Lauderdale-Hollywood International Airport (FLL).
