From a house with little to no windows at all, we moved in to a house with a lot of windows. Good thing the house comes with a set of curtains. The owner chose not to remove them and just gave instructions to wash them from time to time. We were initially planning to get some window blinds or window shades since they eliminate the need for heavy laundering.  

My old room in my parents' house used to have window blinds. They were convenient in a sense that I can control how much light I want to let in the room or whether I want people outside to be able to see what's inside. There are still some windows though that doesn't have any curtains and would look nice with a window shade. It's so nice to prettify an already pretty house.
