Having lived in studio apartments most of my adult life, I've never chosen a bedroom — the whole apartment is the bedroom! But now that I have a family, suddenly there are more people and more rooms involved in the decision-making process...
In our current house, my partner and I have the master bedroom, the 8-year-old has the larger of the two other bedrooms, and the third is our office/guest room. Easy, clearcut, no need for discussion.
Our house-to-be also has three bedrooms, none of which seem master-esque, and so we had to figure out who went where. Upstairs are two 9'x15' bedrooms, the first of which has a large closet (and a closet-in-a-closet), a nice view of the road, west and south exposure, and a large tree right outside the window. The other has a small closet, west and north exposure, and glorious views of pristine prairie. Downstairs is a larger bedroom connected to the living and dining rooms, featuring a medium closet, painted wood paneling, a ceiling fan, and central air (there's only central air downstairs).
After much mulling, we decided to make the larger, downstairs room into the office/guest room, as its larger size will better accommodate a bed for guests as well as two guests. Additionally, it's located in the "public" portion of the house and will save our guests from having to navigate our wonky stairway in the night.
The 8-year-old will get the better-closet, worse-view room, ensuring plenty of space for toys and playing — with a bonus sleeping-in-the-treetops feel. We will take the worse-closet, better-view room, and I very much look forward to gazing out the window each morning. The closet in the office/guest room will supplement our bedroom's limited closet space.
If you live with multiple people in a home with multiple bedrooms, how did you decide who sleeps where?
