Apartment is the 101st level in Chip's Challenge 1. Like many other CC levels, Apartment is rather monotone: the design is completely symmetrical except for Chip, the position of the bugs in the center, and the socket and exit.
The level is made up of 94 cells, most of which are barred by recessed walls on all sides, and includes a large 6x6 central section with four bugs circling its perimeter and four chips in the very center. Apartment can be played through similar to Colony; the route through each cell is LU 3R ULUR 2U LU 2L U (upper left corner) RURDRDR 2D [step 4D RURDR 3D] 3D-R URU 2L UL 2U RULU 3R ULU.
