AAA classifies a Bed and Breakfast as a limited service lodging type with the following definition;

"Usually smaller establishments emphasizing a more personal relationship between operators and guests, leading to an "at home" feeling. Guest units tend to be individually decorated. Rooms may not include some modern amenities such as television and telephones, and may have a shared bathroom. Usually owner-operated, with a common room or parlor, separate from the innkeeper's living quarters, where guests and operators can interact during evening and breakfast hours. Evening office closures are normal. A continental or full, hot breakfast is served and is included in the room rate."
