We have some guests coming over in an hour and I'd like to have our house to have a pleasant smell when they arrive. However, we don't have any air fresheners or anything like that on hand and I have some other things to do to prepare so I don't have time to go get some.
Note that I'm not looking to fix any particular unpleasant smells, but rather attempting to give the house a more prominent pleasant smell.
What can I do to make our house smell a bit better before they get here?
