What things do you clean for company?

The room that you will be entertaining them in. And the guest bathroom.

Kitchen, dining room and potty, close the doors to bedrooms, and enjoy!

The bathrooms for sure- all of them, not just the guest bathroom, because a guest might end up using family bathrooms. The kitchen next. Guests don't feel comfortable if the food is prepared in an unhygienic kitchen. The room where they'll spend the most time next- the dining room. Then the family room or wherever they'll sit after the meal. Then the other rooms should be given a quick go-over because guests may pop their heads into a room for whatever reason.

The bathroom gets cleaned. The dishes get done. The house gets decluttered/picked up. And we vacuum. Those are the most important things to me. I could care less if the windows or washed, or the bed is made, just as long as it appears spotless when you walk in. Regardless if it is actually spotless or not.

Vacuum everything possible! lol Then dust a little so that everything shines. Make sure your drinking glasses are polished and silverware is too. (Our dishwasher kind of leaves spots so do a quicky shine) The seat/back rest of the dining chairs....I have small kids and this gets icky sometimes. The face of your fridge too, nice and neat. Floors and bathroom. Have a great dinner!

Clean all bathrooms (just in case you need all). Clean the kitchen really well. Whatever rooms they'll be in most, dust, vacuum, and de-clutter those rooms. De-clutter all other rooms (not necessary to dust). Run a vacuum through the whole house. Make the beds in all rooms because people might peek. Take out the trash. Throw everything else in closets. Shut doors to rooms you don't have time to clean.

I'd clean the living room, the first floor bathrooms, the dining room and the kitchen, and close the doors to any rooms where you don't want guests to go.
