18101 Collins Ave 5509 Exceptionally rare — very few residences in Sunny Isles Beach offer what this one does. Penthouse 5509 at Trump Palace is a two-story direct oceanfront duplex spanning over 4, 100 square feet with soaring 21-foot ceilings that feel more like a private estate than a condominium. Four bedrooms, 4.5 baths, two full living rooms, and two kitchens — the main upstairs facing the full sweep of the Atlantic, looking north and south along the coastline and wrapping west for breathtaking sunsets over the Intracoastal. Panoramic views from every angle. A dramatic glass staircase connects the levels, setting the tone for a residence as architectural as it is livable. Integrated sound, electric shades, and climate control throughout. The crown jewel: a private 2, 000-square-foot rooftop terrace with your own pool and jacuzzi — no shared deck, no neighbors, just open sky, open water, and a sunset that will reset your perspective on what luxury feels like. At beach level, a rare private air-conditioned beachside cabana with full bathroom steps from the sand — very few units in the building offer this. Full Trump Palace amenities: 1, 000 feet of beachfront, lagoon and lap pools, 8, 000-square-foot spa, fitness center, tennis, and dining. Direct Trump International Hotel access: preferred guest rates, dining discounts, complimentary valet. Fully furnished.
