Perivolas was built some 20 years after the 1956 earthquake had virtually destroyed the cliff side cave dwellings where fishermen once lived. The architecture preserves some elements—wall niches, skylights, handsome stone masonry—of those original dwellings, but it was Perivolas' first-on-the-island infinity pool that put it on the jet-setters' map. That said, today's rooms and suites are seriously comfortable, with lots of dazzling white walls and colorful accents created by scatter cushions and floor coverings. Each unit has a kitchenette and terrace—and as the price goes up, the quarters get larger. The studios have one room, and standard suites usually have a large, open-plan room, often with the bedroom a step or two up from the living area. Superior suites have a separate bedroom, usually slightly set off from the main living quarters by a wall, and often pierced by faux lunette windows. In short, as with most Santorini suites, the bedroom area is not entirely separate from the rest of the suite. The in-house library is a nice touch. The only downside here, as in most of the cave side hotels, is that units are cheek-by-jowl, with conversations easily overheard. That's not the case at the 5-bedroom seaside Perivolas Hideaway Villa, owned by the same people but, naturally, priced for those with extreme means.
