Concierge.com's insider take:
The cost of real estate in this upmarket neighborhood doesn't bear thinking about, but at B+B Belgravia—a duo of Georgian townhouses on a residential street—you could convince yourself that you're at home, and a fine one at that. Belgravia's 21st-century makeover of the bed-and-breakfast concept stripped away chintzy assaults on lodgers' senses—and that uneasy feeling of being charged to stay in some old lady's spare room—in favor of the most minimal of decor. A small lounge area, with checkered floor, black leather sofas, and white chairs, has a flat-screen TV and a complimentary-coffee machine that whips up a passable latte. Breakfast is cooked-to-order in an open kitchen, adding a touch of domesticity. The 17 guest rooms are done in shades of mushroom, cream, and white, with flat-screen TVs and free Internet access. Attic rooms don't have the tall floor-to-ceiling windows of the ground floor, but they do have a cottage-like look and lovely views. It's quieter up there, too—light sleepers on the lower floors should request the rear suites, as the hotel is situated on a sometimes bustling street.
