The station has two entrances on ground level. One is located on Monastiraki square, inside the old station building, and the other is located under a building between Athinas and Themidos Street. Both entrances lead to the concourse level, which is somewhat rectangular with four pathways, one on each side, and an elevator leading to the platforms in the middle. Of the four pathways, two lead to the platforms, one leads to Athinas street exit, while the fourth leads to Line 1's platforms and the Monastiraki square exit. The station has two island platforms, which are noteworthy for being the longest in the whole metro network. The floor, as in every Line 2 and Line 3 station, has granite tiles, the walls are made of concrete, while the ceiling is colored dark gray.
