What are some tips for maintaining a clean apartment?

As mentioned in a previous question, my boyfriend and I are about to move to North Carolina on Saturday. Our apartment in Philly was often the victim of clutter. In packing, we are attempting to rid ourselves of clutter and have everything organized and nice. We’re moving into a pretty classy apartment there, so we’d like to maintain it as a nice living area. What are some tips we should have ahead of time in order to avoid allowing clutter to ruin the aesthetics?
