When booking a holiday on the Greek islands, one of the first concerns is finding somewhere that offers shelter from the Mediterranean sun. If you’re still planning the rest of your trip, our Ultimate Santorini Summer Guide covers getting there, the villages and the beaches. Choosing between centuries-old cave dwellings and brand-new architectural showpieces is a classic dilemma for discerning guests. So which wins: the ingenious engineering of past generations, or modern climate control?
In This Guide
Living Stone Coolness or Digital Climate Control
Traditional cave houses, known as yposkafa, are carved into the thick layers of volcanic tuff and pumice that make up Santorini’s cliffs. The porous volcanic rock acts as a natural temperature regulator. Even when it reaches a punishing 38°C outside, the interior stays remarkably cool, often around 20°C, with little or no need for air conditioning.
It’s one of the most energy-efficient building methods ever devised. The thick walls and surrounding rock stop the summer heat from reaching the rooms inside.
Modern luxury villas in Santorini take a different route to comfort. They rely on multi-zone climate systems, ventilated façades and panoramic argon-filled glazing that blocks infrared heat. With smart controls, you can set the temperature exactly as you like it at the touch of a button.
Light, Architecture and Natural Air Flow
The main weakness of cave living is its shape. Natural light and ventilation usually come only from the front door and a window or two beside it, so the deeper rooms can stay dim even at midday without lamps. Volcanic stone “breathes”, but humidity in an unmodernised cave can climb above 70%, so dehumidifiers are often essential.
Contemporary villas treat space very differently. They’re designed to make the most of the Aegean sun. Their key advantages include:
- Panoramic 180-degree caldera views through sliding glass walls.
- Mechanical ventilation with three-stage filtration against dust and sea salt.
- Open transitions between the interior and terrace, which visually double the living space.
- No stuffy corners or damp patches.
Together, these features remove any sense of being enclosed, so inside and outside flow seamlessly into one another.
Premium Space and the Traveller’s Choice
Authenticity sometimes comes at the cost of practicality. In cave houses, curved vaulted ceilings and narrow passages limit how furniture can be arranged, and open-plan layouts are rarely possible. BlueVillas The Luxury Concept has found a balance between the two: carefully restored historic houses fitted with fully modern engineering.
If you’re after complete silence, privacy and a truly historic setting, a yposkafa will be a delight. The thick stone absorbs almost all outside noise. If you prefer large open spaces, ceilings over three metres high and direct access from your bedroom to an infinity pool, a modern villa is the better choice.
Whichever you choose, Santorini is only one of Greece’s island gems. If you’d like somewhere quieter with plenty of history, take a look at our guide to the best things to do in Chania and where to stay in Chania on Crete.
