When it comes to windows that face a street, I usually gravitate towards top down/bottom up or up/down Roman blinds. Are you familiar with this type of blind? Depending on the manufacturer of the window treatment it is referred to slightly different, but basically it is a Roman blind that can raise from the bottom to the top/middle (first image) or it can be lowered from the top to the bottom/middle (second image.)
Here are the blinds in my son's bedroom.

The benefit of such blinds is that it allows sunlight in while still having privacy from passerbys on the street. I have them in my kitchen (some of the windows face the street), in my son's room (faces the street) and I'm in the process of having some made for my daughter's room. Roman blinds are classic, timeless and this type of system provides great practicality.
