The room is now a friendly place to enter, whether it is night or day.  Previously we had a room-darkening shade.  Ugly!  but functional, of course.  The privacy of the space is perfect, and the light during the day is allowed to enter enough that one knows it is not the middle of the night.  The best part, though, is that the room is considerably warmer.  The window radiates cold, and it is nicely insulated now by the blind.  A triple winner.
