My living room has two sofas in it, one is a big sofa you can crash on like a twin size bed, the second one is a standard size. I make this room semi-private by putting a drape across the door. It will be visually private but you will not have sound privacy. You should be a good or sound sleeper who is not bothered by the sounds of the house if this is your choice so you are not disturbed. Earplugs
can be provided. Please see the pictures in this listing of the beds made up.
