Build a custom cabinet, then put fake drawer fronts on it so it looks like a dresser. Build it so you have more than one compartment, so the whole growing process is contained within that one unit. Use casters on the bottom so it's easy to move. Don't build it so big it won't fit through doorways. Use a duct muffler and a decent-quality carbon filter, along with a low-smell strain. Keep some house plants around, the stinkier the better. Don't tell anyone and *never* leave anything incriminating in your trash.

That said, I still wouldn't do it in an apartment; just too many things out of your control. Dude next door falls asleep with a cigarette and next thing you know, you're in prison, even though you did nothing to draw attention to yourself in any way. But if you do try it, best of luck!
