Welcome to The Sea Ranch, a charming and private 4-bedroom, 2-bathroom beach house located just down the block from Montauk's iconic Ditch Plains Beach-a beloved destination for surfing, sunbathing, beach walks, and soaking up the local scene. While Starlink provides reliable connectivity, The Sea Ranch embraces a laid-back, California coastal aesthetic that encourages guests to unplug, unwind, and fully immerse themselves in Montauk's legendary beach culture. Thoughtfully designed indoor and outdoor spaces create the perfect setting for a restorative off the grid escape to "The End." Designed with both togetherness and privacy in mind, the home's split-level layout offers plenty of space for everyone to spread out while still enjoying time together. Upstairs Living The upper level features a bright, open-concept living area with a premium sound system, comfortable seating, and a fully equipped kitchen complete with a Wolf range and hood. Two bedrooms and a full bathroom are also located on this level, with both bedrooms enjoying access to a private rear balcony. French doors open from the living room onto a spacious front deck, creating seamless indoor-outdoor living. Here you'll find a grill, outdoor dining area, and comfortable lounge seating-perfect for morning coffee, afternoon relaxation, or evening gatherings. Downstairs Retreat The lower level offers an additional layer of privacy, featuring two more bedrooms, a full bathroom, a kitchenette, and a welcoming lounge space with another premium sound system and TV. After a long day at the beach, it's the ideal spot to relax, watch a movie, or enjoy a quiet evening. Outdoor Amenities The property is fully fenced and gated, making it pet-friendly and perfect for outdoor living. Enjoy a large grassy yard, multiple seating areas, an enclosed outdoor shower for rinsing off after the beach, and a cozy fire pit gathering space. Listen to the birds, enjoy the ocean air, and embrace the relaxed Montauk lifestyle. Additional features include multiple split-unit air conditioning systems throughout the home for year-round comfort. Location Just moments from Ditch Plains Beach, the famous Ditch Witch food stand, and all of Montauk's restaurants, shops, and attractions, The Sea Ranch offers the perfect balance of privacy, comfort, and convenience. Coming Soon:A sauna is currently being installed on the property and will be available soon. Optional Add-On:A vehicle is also available for rent during your stay (Turo link available upon request).
