Earlier this summer the fine folks at One Kings Lane visited Greydon House. Here’s what they had to say: Nantucket is a place so storied its nautical-preppy cliché runs the risk of overshadowing its true beauty: its rugged coast; its weathered, shingle-covered buildings; its vibrant gardens. The true nature of this New England island was not lost on the owners of Greydon House, a boutique hotel that opened on the island this past fall. Real-estate-investor brothers Alexander and Jeremy Leventhal and partner Elliot Gould’s Faros Properties had never opened a hotel before. But having summered on nearby Cape Cod as kids and fallen in love with Nantucket as adults, the trio knew they wanted their contribution to the island to feel authentic.
