Love the tips!
Any house, no matter how clean it is will get an odor if it has been closed up for a period of time. Some open windows and a few spritzes of Febreeze will do wonders!
I love that you mentioned about repainting the walls if they seem to soak up all of the light. Thats a must!
Declutter, declutter, declutter. Clutter will only make your closets and cupboards looks smaller than they actually are. Clean them out.
Thanks for the great tips.
