Duke House
This beautifully converted town house (home of the Duke of Gloucester when he was a student) is forever cropping up in British newspaper articles about the best bed-and-breakfasts in the country. The guest rooms sure look like they've been copied from the pages of a lifestyle magazine—swaths of white and ivory, offset by subtle blues or floral accents, envelop the large and comfortable beds like a swanky cocoon. Flat-screen TVs and free Wi-Fi are thoughtful extras, and impeccably chosen local art hangs on the walls in the public areas. The house is a 10-minute walk from King's College.
