Subterranean Byzantine bathhouse
Four subterranean levels carve directly into Mount Taygetos, running as a healing bathhouse rooted in Hippocratic and Chinese medicine.
“This Greek idyll is built into a mountain and has a large spherical pool as its physical and spiritual center.”
What it’s good at
Remarkable
Catacomb-like passages and board-marked concrete carved directly into the Taygetos hillside.
Notable
Hippocratic healing rituals and guided walking trails through the ruins of Byzantine Mystras.
What they say
Michelin Selected
Michelin
Also in Condé Nast Traveler and Wallpaper*.
Even the architecture is transformative: the materials are familiar but the forms are inventive, especially in the spa, which spans four levels.
Tucked away
A place apart: the property is the destination.
Medieval Mystras sits within walking distance up the mountain, surrounded by pine forests and frescoed Byzantine churches.
The rooms
Solid oak furniture and muted Byzantine tones shape the rooms, and most open onto private balconies overlooking the citrus groves.
The water
Bring a swimsuit.
The spa
The marble hammam centers on a heated octagonal slab, and tall windows light the timber-floored yoga studio.
GAIA Restaurant
Regional Peloponnese ingredients shape the Mediterranean menu, served under stone arches or on a terrace overlooking the valley.
The Euphoria Retreat, situated near the Unesco World Heritage Site of Mystras, calls itself the first destination spa in Greece.
At the table
The lounge bar sits beneath a plaster arch, pouring cold-pressed juices, herbal teas, and Greek wines.
How it began

Former banker Marina Efraimoglou conceived the property after surviving cancer, spending a decade searching for this specific mountain slope.
