We worked from home, and saw clients in this room. However it is more than wide enough for a double bed, and we have had people stay in here plenty of times, on the sofabed.

The French Doors make this room a really wonderful space. Seen from the garden, they are on the left below:

Here are a few pics of the room, and the view to the garden

and a temporary resident in one of the oaks outside the window.
