Another vote for flannel sheets and down comforter. With a light cotton blanket in between.
When my parents visit I sleep on an air mattress on the living room floor and they use my bedroom (it's just a 1BR condo). It gets very cold on the floor in the winter. So I spread my fleece snuggie out on top of the flannel bottom sheet and sleep on that, and it's very comfortable. So I would recommend a fleece blanket underneath you as something else to consider.
