Subterranean cliffside guesthouse
Subterranean cliffside guesthouse
Seven suites built into the cliffside run like an intimate home. Days revolve around private terrace breakfasts and the open sea below.
What it’s good at
Remarkable
Earth-sheltered stepped terraces and subterranean rooms carved directly into the Aegean cliffside.
Listed
Three cliffside swimming pools include a twenty-eight-meter lap pool overlooking the Aegean.
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.
The rooms
Subterranean suites draw light through overhead skywells and open onto private terraces. Below, a rock-cut room has its own circular pool.
The pools
Bring a swimsuit.
A 20-meter shared infinity pool stretches across the upper terrace, and paths lead directly to the sea.
At the table
Traditional Cycladic dishes are served at a shaded communal table, and evenings bring local wines.
How it began

A civil engineer spent five years shaping the project with his family, drawing on memories of childhood summers on Syros.

The eight vibes
Design
Built around a vision. Even the door handles have a designer.
Luxe
Cared for at every turn. The bath is drawn before you ask.
Local
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.
Heritage
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.
Classic
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.
Quiet
Away from the crowds. Getting around takes intention.
Secluded
A place apart: the property is the destination.
