Concierge.com's insider take:

This handsome former sea captain's estate turned B&B—near Chatham's classic retail district and a short drive from the beach—is impeccably maintained by the enthusiastic young couple who bought the place in 2006. The 16 rooms are divided among four buildings: the Greek Revival–style main house, built in 1839, with beamed ceilings and walnut plank floors; a historic cottage relocated from Nantucket; a carriage house; and a converted stable. The best room is the Lydia Harding Suite, which takes up the entire second floor of the stable and has two fireplaces, a whirlpool, and a balcony. Several other rooms have whirlpools, too, and all are bright and tastefully decorated in colonial style. The friendly staff—composed almost entirely of hospitality and tourism students recruited from England—serves breakfast and afternoon tea in the airy dining room, which has patio tables overlooking the quiet lawn and garden. Subtle modern amenities, including Wi-Fi, a fitness center, and a heated pool, don't detract from the old-world charm.
