Wow some thing I know about.....
First off did you do a walk through and sign off on any paperwork? check off sheet and Lease?
Second...Is this the apartment you wanted or the only one?....See if you can switch to another apartment.

Other posters gave you some good advice....A cleaning top to bottom....If the ceiling and the walls are painted in a flat base paint this will act as a sponge.....If really bad you may have to clean and repaint to seal in the smoke smell. Use eggshell to semi-gloss paint where you can....

I have used a company to clean with a ionizer machine with mixed results.....may be operator or the amount of smoke....Some homes it worked well in some others not so well..But always an improvement.

If cleaning with bleach water....be careful or you might be buying new carpet when you move out....Also be careful from any cleaning fumes as they may burn your lungs,eyes or worse....
