Easy, clean off the cobwebs, make sure the bathroom is clean & smells okay. Pick up any clothes from the floor. That’s usually enough.
Got o her place instead? 
Anniz is moving here next weekend, and I found the ultimate way to get the place ready: move to a new apartment.
Do the dishes, sweep the floor, do a load of laundry, and come up with a fresh set of excuses as to why there are hairs in my bed that are a different color than hers :D.
–sublight.
Clean the bathroom raw.
Their nuts about bathrooms.
Who’s doing what with whose nuts in what bathroom?
If everything works out- my nuts, my bathroom.
Luck be a lady.
Dave Barry once said something to the effect that women can see individual molecules of dirt; men usually don’t notice dirt particles until they are the size of a large housepet.
So, clean until you think it’s spotless. Then clean for a few more hours. 
Based on observations of my mother and my brother’s wife, women seem to like small decorative touches, like flowers or candles or potpourri. It doesn’t really have to look good, but it does have to look like you made an effort.
I dunno, if a guy has flowers, candles or potpourri, I’m going to think he already has a girlfriend (and she’s living with him). If he has coordinating knickknacks, they’re engaged.
Clean and doesn’t smell is about all I require.
Really, I’m surprised no one’s said the most important thing. After all, the first to do before your girlfriend arrives is to get the other girlfriend out the back door.
If a guy has flowers, candles, and potpourri, and DOESN’T have a girlfriend living there, he’d probably rather have a boyfriend… not that there’s anything wrong with that…
