I set up DH's office in one of the spare bedrooms on the opposite side of the house. It works well because when he is off work, he closes the door. Having that boundary makes a huge difference.
Back when our three kids lived at home I had to set it up in our bedroom, that was not great. I felt like I was sleeping in a storage room with one whole wall filled with shelves and boxes to the ceiling. The room smelled of toner and ink. His desk blocked the window. He would answer the phone or send an email at inappropriate times. I felt like I lived on a shelf, waiting for him to come home for years. I don't miss it.
