What are the room's dimensions?

What size is the room? How many doors are there in the room and leading where? What pieces of her furniture do you plan to keep? What size are they? It would be greatly appreciated if you could supply photos, or room dimensions and furniture sizes.

Maybe your daughter and her husband could sleep on an inflatable bed. But if you want to keep an actual bed for them, you'll want to give them at least a queen size bed (60x80"). A wall mounted TV takes up almost no space. So there might be space left for 2 comfortable chairs with a small table between them.

Perhaps the bed itself could be utilized for seating. In Hawaii, people push a bed against a wall, supply it with plenty of big pillows, and use it like a really deep sofa.

With more information from you, you'll get a lot more info from us.
