Curtains will look good and reduce the noisy echoes from the tile floor.

Could we see the whole space ? Drapes are a nice choice in a tiled space since they absorb sound . Do you need heat and UV control too or just privacy.Your pillows are too big and too many for sure., How can anyone even sit on the sofa. I don’t have a feel for the space without pics of it all.

The pillows were just thrown there right after we moved. They are not still all on the couch like that. I’ll attach more photos of the space

This question frequently comes up. It is such a personal decision based on whether or not you need heat/light/privacy control. Do you open your windows? Do you want to see your view? What kind of look do you prefer?

I do not use any shades that can be seen during the day. They come down in the bathrooms after dark. I greatly dislike shades that cover the windows 24/7. How do your window treatments look from the outside? I always prefer curtains or shutters because I like that look. Dark blinds or shades create a cave-like feeling. Do you want light/bright interiors?

Something is off with the rug.......

are you installing more seating?

Should the loveseat be on the opposite side?

move the sofa out away from the windows by 6" to allow for the drapery panels.

You could always do both. Shades or blinds for function, curtains for softness.

I love your rug, BTW, but you can do much better on the pillows (and probably could stand to lose two of them).
