Hmmm, good question. Wasn't ever an issue when I was in college. Now that I'm single again, the only guy I've dated, I went to his place (had travelled to his town - long story).
It was good for me - nice to be somewhere different, in the new guy's space. BUT - he was a major slob, I didn't mind at all but most women would have been turned off. If a guy's space isn't really clean, should go to the girl's house.
Plus - to tell you the truth - I snooped at his place while he was at work. (In my defense, I was just trying to make sure he wasn't an ax murderer). Found a few things he probably wouldn't have wanted me to see.
So - if you have anything to hide, or you're a lousy housekeeper - go to their place!
