I don't know if you visit reddit and have already seen this...
But for what it's worth its an AMA (ask me anything) of a bike thief on the motorcycle subforum. You'll get alot of advice from a former thief about what works and what doesn't.
Some interesting tidbits:

But as a TLDR: Safest option is to get a secured storage outside of your condo. If they can't see it they can't steal it. They would have to break open each lock inside the storage just to figure whats inside, not worth the time/risk if its not an expensive bike or some junk, plus the secured gates prevent entry or exit from random people, so if a bike does get stolen it HAS to be an inside job from a secured storage, not worth the risk for the facility either.
