Welcome to The Koi Marlin by AvantStay — where Zen meets the sea in the heart of Port Aransas. Tucked just minutes from the beach and surrounded by the laid-back charm of this beloved coastal town, this serene retreat blends thoughtful design with breezy outdoor living. With easy access to local marinas, eateries, and the golf cart zone, your group can unwind and explore with ease.

Inside, the open-concept layout invites connection and comfort. A full kitchen and dedicated coffee corner set the tone for slow mornings, while the dining table for eight and spacious living room—complete with a large TV and fireplace—make it easy to gather after sun-soaked days. Each of the three bedrooms offers a plush queen or king bed, including a unique dual-bed primary suite that sleeps four. A sleeper sofa in the living room offers additional space for groups up to ten.

Step outside and let the rhythm of coastal living take over. A sparkling private pool, koi pond, and wooden boardwalk offer moments of reflection, while the grill, lounge seating, and pergola-covered area are ideal for golden hour gatherings. Whether you're sipping coffee under the palms or watching the sunset with friends, The Koi Marlin invites you to slow down, connect, and soak it all in.

Whether it’s a family trip or a friends’ getaway, The Koi Marlin is ready to be your crew’s next Port A favorite.
