Having a similar issue and trying to determine if and how to fasten a trellis to outside wall since Im on the 1st floor. Or nice-looking lattice if I can find any. Then growing a speedy annual vine on it until I can get a perennial established such as Wisteria. In theory Ill have scent and flowers to screen out my neighbors while still letting in light and air in the summer. On higher floors you might try a window box and plant a living screen with or without a trellis.
Finally instead of window film in case you were thinking of using it there is a glass-frosting spray paint I just used on my bathroom window which so far is working out great. I got it at Michael's. It covered very evenly and opaquely. It smells though when you apply it and have to use acetone to remove it but so far I'm much happier with it than the window films that kept peeling off both the windows where I applied them.
Good luck!
