How to get house ready for viewing with boxes everywhere?

[Letmesleepalready]

We're moving out of our rental soon, and the estate agents have arranged a viewing before we've moved out. (We've said yes, without thinking!) What do we do with all the boxes everywhere? We can hardly walk in our living room at the moment!

You don't need to do anything
It's rented
It's not like you need to sell it
Just leave it as it is

Really? It's the first visit we've had to do, all our past landlords waited until we'd moved out!
