One&Only Hotels in Europe: Continental Luxury

Golden sunlight drifts over Kea Island’s whitewashed lanes, dappling pools and elevated terraces. Aesthesis hums with unexpected details: a hidden atelier, a courtyard that smells of jasmine and espresso. Portonovi’s Adriatic coast curves like it was drawn for private eyes – all cobbled streets and water so clear, you’ll double-check your lens. One&Only’s entire luxury hotel portfolio is quietly confident, never loud, and full of moments you didn’t see coming, but in One&Only Hotels in Europe especially, luxury lives in the small pleasures: olive oil pressed that morning, a cocktail poured just so, a view that feels exclusive. And if you’re still searching for something spectacular for summer - but you perhaps feel like you’ve seen it all - they’re a very compelling place to start… 

One&Only Kea Island

Kea Island, Greece

Occupying a vast 65‑hectare cliffside site on Kéa’s west coast, One&Only Kea Island is a new kind of refuge – an all‑villa sanctuary of private infinity pools and endless Aegean views.

Set within Vroskopos Bay’s calm turquoise waters, the resort feels beautifully integrated into its surroundings – a dialogue intentionally executed by architect John Heah. 63 villas nestle into the landscape with crisp white walls, hand‑cut stone and airy pergolas, honouring the island’s rhythm, its artisanal heritage and its quieter side of the Cyclades – just a short speedboat hop from Athens, yet worlds away in mood.

At the heart of the experience is a slate of culinary spaces that mirror the island’s seasons – from Atria, where Greek classics and fresh catch arrive with a graceful twist, to the ocean‑view Kaiki pool bar and the intimate Èpicora wine lounge, showcasing local labels and artisanal pairings. A hidden bar called Incognito, behind an unmarked door, serves rare spirits and cocktails in a cosy, speakeasy vibe.

Villa living at One&Only Kea Island is generous and private: one‑ and two‑bedroom cliffside retreats open to courtyards, fireplaces and uninterrupted sea horizons, each with its own infinity pool inviting early dips and golden‑hour swims. Interiors combine Mediterranean light with thoughtful comforts – from vaulted ceilings to floor‑to‑ceiling glass that blurs the line between inside and the Aegean beyond.

For moments off‑villa, the resort’s wellness offerings are compelling: a three‑level One&Only Spa with indoor‑outdoor pools and holistic treatments inspired by elemental balance, steam rooms and relaxation spaces designed to ground as much as rejuvenate. 

Beyond its shores, curated adventures - from diving into historic shipwrecks and yacht charters to archaeological hikes and cultural tours - invite guests into Kéa’s layered stories, placing the resort firmly in the landscape rather than above it. As part of One&Only hotels in Europe, it offers a refreshing take on Greek island luxury. 

One&Only Aesthesis

Athens, Greece

Sat on a sunlit sweep of Glyfada’s chic waterfront, One&Only Aesthesis is a new kind of Riviera escape – an elegant bloom of mid‑century glamour and edge‑of‑sea ease just 30 minutes from Athens. Located within a protected 21‑hectare beachfront and forest reserve, the resort feels as if the golden age of the Athenian Riviera has been reimagined, with low‑slung bungalows, sweeping terraces and private pools that frame the glittering Saronic Sea. More than a place to pause, One&Only Aesthesis is a destination of its own, and one of One&Only's standout stays in Europe.

The resort’s spaces celebrate this meeting of land and sea: rooms, suites, villas and private homes clad in natural materials, muted tones and woven textures open to gardens or astoundingly wide terraces, creating an easy indoor‑outdoor rhythm that feels at once timeless and curated. Mid‑century lines and luminous proportions make sure every stay feels both personal and lived‑in.

As with any One&Only property, the food is a real narrative of place. From Ora by Ettore Botrini’s creative Mediterranean menus to a beachfront concept elevated by Peruvian flair and that stunning Aegean backdrop, dining can be as relaxed or as lively as the moment demands. Three bars - leafy garden‑inspired Alelia, poolside Minima and sunset‑facing Thimisi - all nod to Glyfada’s iconic social scene.

Wellbeing and play are woven into the resort’s rhythm too, from the very first Guerlain Spa in Greece - where personalised rituals and sun‑dappled treatment spaces meet the calm of the coast - to Club One’s fitness, tennis and padel spaces and nature‑inspired KidsOnly programming for younger travellers.

Off‑resort, One&Only Aesthesis’s location naturally calls for discovery: sail the Argo‑Saronic Gulf, meander along fragrant pine garden paths or explore Athens’s ancient wonders – all are within easy reach of this glamorous hideaway.

One&Only Portonovi

Boka Bay, Montenegro

At the elegant entrance to Montenegro’s Boka Bay, One&Only Portonovi is a grand harbour‑side retreat – a resort where mountain silhouettes and rich blue waters meet Venetian‑inspired architecture and the brand’s famous world‑class service. Completing One&Only hotels in Europe, it offers a strikingly different side to luxury on the continent. 

Framed by colonnades, terracotta rooftops and far-reaching bay views, the resort’s 140‑plus rooms, suites, villas and private homes have the Adriatic incorporated into their design – each space is conceived to draw the water in, whether through expansive terraces, balconies or floor‑to‑ceiling windows that let light and sea air mingle with the interiors’ calm palettes.

Dining is a rendezvous of flavour and landscape: Sabia serves refined Southern Italian favourites and fresh seafood with Giorgio Locatelli’s unique spin, while Tapasake Club is alive with Asian fusion plates, cocktails and poolside energy. Meanwhile, La Veranda celebrates delicious Montenegrin classics and local produce with modern finesse, perfect for a leisurely lunch or a sunset dinner overlooking the bay. 

Wellness - as ever - is equally remarkable. The Chenot Espace wellness centre brings the Swiss‑refined Chenot Method® to the Adriatic: a holistic suite of treatments, detox programmes and therapies all designed to recalibrate body and mind, with steam rooms, movement studios and restorative spaces set against views of sea and mountains.

Pools and play are dotted throughout the One&Only Portonovi estate: from tranquil infinity edges overlooking the bay to a private white‑sand beach club and water sports that make the most of this quiet sheltered cove. For families and active travellers, tennis, yoga or sailing adventures on the Adriatic are all easily arranged. 

Beyond the resort’s threshold lies the historic beauty of Montenegro - cobbled old towns, hidden bays, lofty peaks ripe for exploration - while at Portonovi itself, Michelin-worthy dining, bespoke experiences and views that shift with every hour of light make this Adriatic refuge a compelling chapter for One&Only Hotels in Europe.

Hallmarks of Every One&Only Stay

No matter which address you choose, there are a few signatures that run through One&Only's European Collection — and, indeed, every One&Only resort around the world.

• One-of-a-kind destinations – Every resort occupies an extraordinary location chosen for its natural beauty and cultural character, rather than simply ticking a map.
• No two resorts are alike – Each property is designed around the personality of its destination, with its own architecture, story and sense of place.
• Warm, personalised service – Intuitive hospitality sits at the heart of the brand, with every stay tailored to the individual rather than following a script.
• Destination-led dining – Expect acclaimed chefs, local ingredients and restaurants that reflect where you are, rather than offering the same menus from one resort to the next.
• Transformative wellness – From world-renowned spa partners to treatments inspired by local traditions, wellbeing is woven into every stay.
• Experiences you can't replicate elsewhere – Private guides, cultural encounters, outdoor adventures and bespoke itineraries connect guests with each destination in meaningful ways.
• Space to celebrate every occasion – Whether it's a honeymoon, a family gathering or simply time together, each resort is designed to bring people together without ever feeling crowded.

The beauty of One&Only Hotels in Europe is that no two stays feel remotely alike. One immerses you in the quieter corners of the Cyclades, another revives the glamour of the Athenian Riviera, while a third opens the door to the Adriatic's hidden treasures. Different landscapes, different personalities, but the same effortless attention to detail running through each one. If you're looking for a European escape that feels genuinely fresh, this is where to begin.
