An aircraft cabin module for passengers that includes two transverse walls extending from a longitudinal cabin wall up to a longitudinal aisle, at least one of the transverse walls including a transparent portion. A longitudinal wall separates the cabin module from the aisle. At least one service module is arranged between the two transverse walls, more or less symmetrically in relation to a transverse median plane, defining with the walls of the module two contiguous personal spaces. An access is provided from the aisle to each personal space, and at least one seat is provided in each personal space, each seat having at least one configuration in which it is positioned parallel to the cabin wall. Each personal space includes elements capable of forming a bedding surface for at least one passenger.
