Recommended window treatment places?

we used budget blinds; relatively painless and has an alleged no questions asked 5 year replacement guarantee

There are some places I see in the hood with those walls that are all window.

One of those is right behind me and I see it from the back porch. Yeah, they paid a million for the apartment but now can"t afford to cover the windows and there are sheets hanging off the windows because the fabric length does cover up their private moments.

And in same building there is someone who hasn't bothered to cover them at all and all those summer evenings I see him working out with weights, looking sweaty (and not appealing at all) in his skivies. I think he thinks that if he paid that much for the apartment then he must be invisible.
