The station of line 1, in curve, is of standard configuration. It has two platforms separated by the tracks of the metro and the vault is elliptical. The decoration is red Ouï-dire style. The lighting canopies, of the same color, are supported by a curved support in the shape of a scythe. The direct lighting is white while the indirect lighting, projected on the vault, is multicolored. The white ceramic tiles are flat and cover the walls, the vault (diagonally), the tympans and some of the hallways. The advertising frames are white and cylindrical and the platforms are fitted with silver sit-stand benches as well as platform screen doors.

The station of line 2, also in a curve, is equipped with a central platform framed by two tracks, with the southern one being bordered by a 'dead platform' protected by a fence and partially used as a connecting passage, which connects with the platform in the direction of La Défense station from the line 1 station adjoining it. Established flush with the walls, its ceiling consists of a metal deck, whose beams, silver in color, are supported by vertical walls. The decoration is in the Mouton-Duvernet style, but with an orange beveled tiling on the walls and the outlets of connecting corridors with line 1, a feature that was also found in the station of line 9 before its renovation; in addition, they are aligned horizontally and vertically. The lighting canopies are specific, fitted with metal blades. The advertising frames are also metallic and the 'shell' seats, characteristic of the Motte style, are blue.

The station on line 6, like that on line 2, has two tracks framing an island platform. However, it is the only one that is not curved and the vault is elliptical. The decoration is a particular variation of the Mouton style with two characteristic lighting canopies, walls covered with tiles, with unique patterns on the network, aligned horizontally and vertically, as well as a vault painted white. The surrounds of the staircase hoppers are treated with the same tiling for some or with a flat white tiling also aligned horizontally and vertically for others. The advertising frames are metallic and gray, and the platform is equipped with a few white Motte style seats.

Like that of line 1, the station of line 9 is curved and has a classic layout under an elliptical vault. Its decoration is of the style used for most metro stations. The lighting canopies are white and rounded in the Gaudin style of the revival of the renouveau du métro des années 2000, and the bevelled white ceramic tiles cover the walls, the vault and the tympans. The advertising frames are in white ceramics and the seats, in Akiko style, are green. The western part of the platform, in the direction of Mairie de Montreuil, has the distinction of displaying coats of arms of the two French departments of the Antilles: Guadeloupe and Martinique, thus illustrating the subtitle attributed to the platforms of line 9 only.

For each stopping point, the name of the station is written in Parisine font on enamelled plates.
