Look good: Smells good
Once you have removed odors, you can add back in some pleasant smells. These should be subtle. For safety DO NOT leave lighted candles throughout your house. There are safer alternatives. One option is to use plug-in air fresheners. Another is to use scent pods. Gold Canyon is a company (and former client) that has a sugar cookie scent (goldcanyon.com/sugar-cookie-scent-pod) and oatmeal cookie (goldcanyon.com/spiced-oatmeal-cookie-scent-pod). The pods require a warmer to activate the scents. These can be found at goldcanyon.com/warmers. Pod warmers come in many different styles to blend into your decor. The warmers come with an automatic shut off. You will have that just baked smell with no effort.
