Six of the best: cave hotels
Once upon a time we all lived in caves. Most of us moved on and created more comfortable places to stay, but here and there – from the Greek Islands to the Loire Valley – these ancient digs have been spiffed up into romantic boutique hotels with troglodyte-chic rooms: spare, monastic, simply but exquisitely furnished. In the modern world there remains something primitively appealing about sleeping in a cave. A safe retreat, dark and soundless; a bolthole in the belly of the Earth.
