PB hotel design editorial

Planted on a five-acre peninsula where the Atlantic meets the Gulf of Mexico in Marathon, Florida, Isla Bella Beach Resort arrived in 2018 as a rare attempt to give the Middle Keys a resort of genuine architectural ambition. The low-rise buildings draw on the vernacular of traditional Florida coastal construction — white-painted clapboard cladding, deep wraparound verandas stacked across three floors, X-pattern balustrade panels, and cedar-toned deck stairs stepping directly onto the sand — producing a massing that suggests a well-established fishing community rather than a purpose-built resort. Blue-painted window surrounds and louvred details tie the exterior palette to the water on both sides. Inside, the interiors strike a balance between crisp resort white and the saturated blues of the surrounding sea. Rooms are furnished with lacquered white case pieces, silver-glazed ceramic lamps, and deep navy geometric carpet, while floor-to-ceiling curtains in a bold indigo palm-tree print — a pattern that recurs across roman blinds and scatter cushions — carry a confident tropical personality without tipping into kitsch. The pool pavilion, capped with a ribbed pyramidal roof, sets wicker chaise longues in geometric-patterned cushions against limestone-toned pool decking, blue-and-white striped umbrellas completing the nautical register. The waterfront restaurant opens its walls entirely to the bay, rattan armchairs and encaustic-patterned floor tiles grounding the dining room in a vernacular that feels closer to the Florida Keys' own material culture than to generic resort hospitality.

Isla Bella Beach Resort Reviews

"Great property. Lots of things to do and accommodation. Worth the price to stay but… we ordered room service and it come with missing items that said they would come with the room. And when we called they said that they would listen to the call. It took over 45 min for the missing items to come. We also ordered the cheese pizza it was not cut at all. For a $24 pizza it tasted like $5. For an expensive hotel I rate it an A+ but room service an F"

"We stayed here for our 1st time for our anniversary and it was wonderful. Views, multiple pools, food, drinks & staff are wonderful. Only negative things were closing off the area every night to watch sunsets, wood on balcony's no privacy & not enough restaurant choices to stay on resort."

"The accommodations looked promising and high-end; however, our first day and a half was a disaster. There were drunk teenagers on a senior trip who were pounding on doors, screaming in rooms and hallways, and kept us up all night. We called security, and it stopped for a bit, then continued throughout the entire night. Not exactly a pleasant experience. The resort responded by apologizing and waiving fees that they said were already integrated into the booking fee. They should have done a lot more to make our stay pleasant after what we endured. I had a positive experience at the spa with a facial and a massage."

"Isla Bella is a beautiful resort in Marathon. It's a perfect stop between Key Largo and Key West. My husband and I spent our 19th Anniversary there. The staff is wonderful, friendly and helpful. We had a bungalow on the beach and it was perfect for us. We look forward to returning soon."
