Safer Places to Live for a Month in Cancun, Off the Beach

My girlfriend lives in Cancun, she is Mexicana.  My business is done entirely via the internet, so I can work from anywhere in the world.

I want to rent a nice place (1 BR) for a month to visit her while also working.  Would prefer to not stay in the Hotel Zone just because of all the energy, noise, etc.

What is a safe place to stay that is secure, and nicer than average.  Price is moderately important, but I realize I have to pay a little more to stay in a nicer and secure location.

Thanks everyone.
