Each platform has very long and thick wall-like columns, spanning for three quarters of the station, allowing access between the M1 and M4 sections through 6 points.

The design of the two sides, although part of the same station and even the same platform, is quite different – the M1 side features white-grey marble walls and floors, with a grey travertine roof arranged as to form a square grid, lit by square white fluorescent neon lights built inside the grid while the M4 side features orange synthetic walls, black Azul Noce granite on the floors, and yellow neon lighting running in a continuous line along the station, above the tracks.

The station is usually announced in trains at Gara de Nord, Grivița, and Crângași as "the place to switch between M1 and M4".

The M4 station was opened on 1 March 2000 as part of the inaugural section of the line from Gara de Nord to 1 Mai.

[1] The Basarab metro station was added after Line M1 was finished, with the sole intent of providing a means to change from M1 to M4.
