Level 188 is an enclosed edifice, with architecture resembling that of a hotel. A large courtyard-like area is present in the center of the level, surrounded on all sides by numerous small square-shaped windows on each wall. One can enter the interior corridors of Level 188 via a stairwell present near one end of the center courtyard. These hallways, each interconnected to reach five floors, loop around the level and lead to the interior rooms behind each window.
