Office.
I have been working from my bedroom for the past seven years since starting to work for EF.
I finally have a proper office. Since my older daughter moved out to live with her boyfriend, and this space wasn't being used in the house, I have converted it into an office.
I still have a nice red Persian rug coming to fill in the middle of the room.
I especially like working with two monitors, and not having to share with my television in my bedroom.
