I had the carpets removed about 9 months ago and replaced with linoleum. After removing the carpets and ensuring that there was no rot, the tech installed 1/4-inch plywood, covering all cracks and screw heads to have a smooth finish. There is a steel frame member just where the fridge is, and thus there is a bit of a rise there. Carpets hide a myriad of flaws, but flooring doesn't. BTW, the linoleum looks like and feels like snap in flooring, but it is one piece from the from the the step to the bedroom. The flooring matches the oak cabinets, and the tech used matching stained oak trim.
