I had the opportunity to do that a few years ago. I have no pets and awful allergies. What I felt was important was natural light, soft white walls, a walk-in closet with shelves, a dedicated iron circuit by a window, a place for the computer, and light cream, very short carpet that shows every dropped pin. Oh, and adjacent laundry. If the laundry were anywhere else, I'd never get it done.
hugs,
