What they say

Also in Condé Nast Traveler.

The design is warm and minimal, with earth tones, natural materials, and curved walls that feel like something from another time and place.

Tucked away

A place apart: the property is the destination.

On ten acres of untouched cliffside in Tria Lagonia, above the Aegean on southwest Syros.

Bring a swimsuit.

A 20-meter shared infinity pool stretches across the upper terrace, and paths lead directly to the sea.

Built around a vision. Even the door handles have a designer.

Cared for at every turn. The bath is drawn before you ask.

It could only be here. You wake up knowing where you are.

Social

Where the city goes out. The bar is full and the night is young.

A building with a story. Once a palace, a monastery, a station.

Wellness

You leave feeling new. Rest, sweat, soak and sleep like a stone.

The city grew up with it. Same rituals, same regulars, same bar.

Resort

A world of its own. Something to do from breakfast to nightcap.

The scene

Lively

Where things happen: restaurants, shops, people.

Central

Well-located: walkable to some things, a short ride to more.

Away from the crowds. Getting around takes intention.
