Apartment An apartment (American English), flat (British English) or unit (Australian English), is a self-contained housing unit (a type of residential real estate) that occupies only part of a building, generally on a single level. Such a building may be called an "apartment building", "apartment complex", "flat complex", "block of flats", "tower block", "high-rise" or, occasionally "mansion block" (in British English), especially if it consists of many apartments for rent. In Scotland, it is called a block of flats or, if it is a traditional sandstone building, a "tenement", which has a pejorative connotation elsewhere. Apartments may be owned by an "owner/occupier", by leasehold tenure or rented by "tenants" (two types of housing tenure).
Chambre de bonne A chambre de bonne is a type of French apartment consisting of a single room in a middle-class house or apartment building. It is generally found on the top floor and only accessible by a staircase, sometimes a separate "service staircase". Initially, these rooms were intended as the bedroom for one of the family's domestics, and the name originates from the colloquial name for such maids: a "bonne à tout faire". Today, "chambres de bonne" are usually the cheapest rung on the Parisian letting market, and are primarily rented by less well-off workers and students. They are also in high demand among workers who wish to maintain a small room or postal address in a big city, especially Paris.
