About this home
15208 GULF BOULEVARD UNIT 601
Crowning the top floor of Sereno, this southwest corner penthouse commands a rare position—one where the Gulf unfolds endlessly and the coastline stretches uninterrupted, untouched by neighboring towers. It is, quite simply, the most expansive residence in the building. Encompassing 3,420 square feet, the home is both grand and composed. Volume ceilings finished with crown molding and wide-plank wood floors create a sense of quiet sophistication. Floor to ceiling glass dissolves the boundary between interior and the Gulf. At the heart of the residence, a beautifully scaled kitchen with an oversized island and breakfast bar invites both intimate mornings and effortless entertaining. The primary suite is a private sanctuary, opening directly to a Gulf-front terrace where sunrise and sunset become daily rituals. Primary bath features double vanities, a walk in shower and travertine marble flooring. Two guest suites, each with en-suite baths, offer refined accommodations, while a flexible fourth bedroom or media lounge adapts to the rhythm of the home. Additional terraces reveal a softer vantage point—overlooking the calm waters of Boca Ciega Bay. Set along one of Madeira Beach’s most coveted stretches of sand, Sereno is a study in understated coastal modernism. With over four acres of pristine Gulf frontage and nearly 480 feet of uninterrupted shoreline, the six-story midrise is intentionally scaled for discretion and privacy. Just 44 residences share this address, fostering a sense of space and tranquility rarely found along Florida’s coastline. Two secured garage spaces and private storage—conveniently positioned near the pool and direct beach access—complete the offering.

Value check
Is the price right?
The internet’s favorite home-value number comes from a single automated model that has never seen the street, the finishes, or the view — which is why it routinely misses by tens of thousands of dollars. The edgeAI estimate combines multiple independent data sources with our team’s on-the-ground expertise in this exact market.
