Lois has Clarkie bear in her bed in "Resurrection." Another ep with a good shot of her bedroom/bathroom is "We Have A Lot to Talk About," when she comes into the bedroom from her bathroom and the bomb is hooked up to the exercise mat.
We also get some looks at Clark's bedroom in "Home is Where the Hurt is" and "Never on Sunday" and the kitchen at the end of "Chi of Steel."
Good panoramic views of Lois' living room/kitchen when Clark and Ching are preparing for battle in "Battleground Earth."
I would say that Lois lives in a pretty typical one-bedroom apartment, and that Clark lives in a loft. I think Lois' bedroom is connected to her bathroom.
