If the walls are a neutral beige color then yes, leave them as they are.
As for removing personal stuff, I would do that anyway. Never know what kind of crazy person might be coming into your house.
that is a good point. i'm going to take my girly stuff down and pack it up, but i thought taking my picture frames and photos off the walls was a little weird
Seen it all, done it all, can't remember most of it!
