About the host
Hosted by Kim Portner
Our journey to the Florida Keys began in 2009, when we vacationed here for the first time and instantly fell in love with the laid-back lifestyle, the vibrant oceanfront scenery, and the warm, welcoming community. What started as a family getaway quickly grew into a lifelong passion.
Driven by our love for the Keys, we founded HappyintheKeys — a lifestyle brand and a curated collection of luxury vacation rental residences. We didn’t just want to buy a house here; we wanted to build experiences that capture the essence of what makes the Keys so special.
Each home in our portfolio, including Grouper House, is custom-designed and personally managed by us. We focus on quality, comfort, and thoughtful design to ensure that every guest feels like they’re coming home — whether it’s their first visit or their tenth.
From the architecture to the furnishings, the amenities to the small details, everything has been carefully selected to create an effortless, elevated vacation experience. We believe luxury should feel personal, and we’re proud to offer a stay that reflects the beauty and authenticity of life in the Florida Keys.
When you stay with HappyintheKeys, you're not just renting a house — you're stepping into a slice of paradise we’ve lovingly crafted and are excited to share.
Why they chose this property
We custom designed and built Grouper House — along with several of our other homes — specifically with the vacation lifestyle in mind. As avid travelers and hosts, we understand what makes a getaway truly special: comfort, privacy, space, and a setting that brings people together effortlessly.
This home was thoughtfully created for families and groups of friends traveling together. Whether it's multiple couples, an extended family, or a mix of both, everyone deserves to feel equally pampered. That’s why Grouper House features four identical Master Suites, each offering the same spacious layout, high-end furnishings, King-size Purple™ mattresses, en-suite bathrooms, and private patio access. No one has to compromise — every guest enjoys the same level of comfort and luxury.
We built this home to make vacationing together easy and enjoyable, with generous indoor and outdoor gathering spaces, a resort-style pool, and premium amenities designed for relaxation and fun. From quiet morning coffee on the terrace to sunset cocktails by the pool, Grouper House is meant to be shared, enjoyed, and remembered.
This property isn’t just a rental — it’s a destination tailored for those who want more than just a place to stay. It’s a home designed for making memories.
What makes this property unique
Grouper House was thoughtfully designed and custom built — along with two of our other luxury homes — to meet the specific needs of vacationing families and groups of friends. As owners and frequent travelers ourselves, we understand the value of equal comfort and privacy when staying with others.
That’s why this home features four equally spacious and beautifully appointed Master Suites, each with a King-size Purple™ mattress, en-suite bathroom, private wine/coffee bar, and direct access to patio or terrace space. Whether you're traveling with other couples, extended family, or friends with children, everyone enjoys the same level of luxury — no drawing straws for the “best room.”
Beyond the interior, Grouper House offers a host of unique outdoor amenities designed to elevate your experience:
🚤 Private Boat Ramp — A rare and valuable feature in the Keys, our ramp is reserved exclusively for guests of our five homes and our personal use. It’s ideal for guests who bring their own boats and want convenient, secure water access. 🛥️ Extra-Wide IPE Dock — Built for both comfort and function, the dock offers plenty of space for boarding, unloading, or simply relaxing. It’s also a great spot for fishing or spotting manatees cruising the canal. 🏊 Expansive Pool Area — The large saline pool is thoughtfully positioned between the home and the dock for easy access and stunning views. A splash deck makes it perfect for kids, while the surrounding lounge area invites relaxation in sun or shade. A Bathroom is convenient to the pool and dock.
From the indoor layout to the outdoor design, Grouper House delivers the perfect balance of luxury, function, and family-friendly features, making it a standout destination for travelers seeking an elevated Florida Keys experience.
