I am moving in to a three story apartment. The first floor is a large sunroom with a sitting room all connected with open doorways. Nice. The second floor has one bedroom (we converted to an office/laundry room) a full bathroom and a largish open room with a kitchen and extra space. The third floor is three bedrooms and a bath. There are only three of us so I don't foresee needing lots of dining space. I want to put a dinette set in but because of the layout I see people hanging out on this floor alot. I also want to put in a sofa. My young adult son is making faces, saying it will look odd and cluttered. There room is long and rectangular with a wall of three windows. I could put the sofa there but I do still want lots of airflow. The television and entertainment stuff will be going on the first floor where the sunroom is. Any tips?
