Someday when I build a strawbale house in the desert it will have a setup like this- I think the bottom is a trundle bed. But it might not work since my house made of straw and mud will probably have no straight lines.
Avoid over decorating the guest bedroom. You want it to be comfortable and welcoming but not so full of decorative objects and furniture that guests have no place to put their things. Leave room to make this their home for the duration of their stay. If you have only one guest room, choose twin beds over a double or queen-size bed; that way friends, children, or couples can occupy the room comfortably. A shared table serves both beds as a place for an alarm clock and personal items.
