The rental house I lived in for 5 years while I searched for house to renovate was very dark and depressing. Hardly any sunlight came in through the windows (by design--to keep the house cool). I need bright and airy rooms and I am so happy with the abundant sunshine in my upstairs hallway. One of my favorite spots in the entire house. When I clean the floors I love to fling open all the windows to let the breeze float in.
