Great ideas here! I would hate to give up the illusion of space and added reflective light from the mirrors, so I'm for:
-Hanging a curtain. A sheer fabric will mean you can keep the advantages of the light, while softening the effect
-One idea you should definitely consider is leaving one panel (the one that doesn't reflect the bed perhaps) as a mirror.
@Remy, it's hard to not to be nervous at first. Concentrate on your lemon tree and buy a small easy care potted plant for your new home. If you have a green thumb, get a new collection.
After a few of my moves I experienced feelings of anxiety for a few weeks. Some time later I read about things that increase stress levels and moving house was high on the list. It leaves quickly, however.
