Make the room able to be DARK at night for sleeping. So many places have these fancy curtains that looks great but have big gaps at the top, bottom, or where the curtains meet.

If the TV is in an armoire make it able to be pulled out far enough and rotated that I don't have to sit right in front of it to see it.

As others have said, an outlet right by the bed. I use my iPhone as my alarm clock and it woule be nice to be able to charge it overnigth while doing so.
