I try to keep the lighting in the room the same... dark with ambient lighting positioned as not to cause glare on the screen. I say dark because the surrounding environment can cause distraction and even color cast, tricking your eyes into seeing the photo differently than it would display otherwise. Minimizing the modules on the LR interface and changing the background to black also seems to aid in helping your eyes visualize the proper exposure and color correction. I say "proper" and not "correct" because for the most part, post processing is a subjective experience.
That being said, what looks good to you today may not look right to you tomorrow. Even when all other factors are equal, our own subjective opinions may change.
I've also noticed that upgrading from LR3 to LR4 has changed my opinion on how the process many of my images. I've gone back numerous times and updated the process to rework the photo in LR4. With the improved controls, there are ever more possibilities within our reach to manipulate a photo to increase its eye appeal.
