On the right side are two sets of escalators, one going up and one going down, with glass and metal railings. On the left, there is a long wall with linear light fixtures running along the ceiling. There are signs indicating the direction of the subway lines: "Хаджи Димитър" (Hadzhi Dimitar), "ж.к.Овча купел" (Ovcha Kupel), and "Горна баня" (Gorna Banya). There are also "No Entry" signs in Bulgarian and English: "Не е вход" and "Not an entrance". A few people are visible in the distance along the hallway.
