Windows and a balcony are nice, especially is the noise level there is low enough that you can do things outdoors with low noise, like the rather famous ranting, especially if there is a little ambient noise ( wind in trees, birds but no trucks and car noise) to add to it. Plus wind ruffling the air, plus you can always end by simply panning to the balcony, walking in front looking out and away from the camera, and give the parting words. Always gives the dramatic feel, plus now you do have somebody to be the second unit operator, and room to actually have a second POV would be nice.
South or East facing so low ambient light level for a part of the day so a white curtain across the window ( plain white cotton curtain, full length and preferably 2 layer for the sound damping it gives) gives a nice even light. North or West facing all day light, but shadows and likely you will have too much ambient light at times for good even lighting.
I like the idea offered above of the Buy a Brick option, as you can buy a whole load of thin brick facing, and simply set up a frame of shutterply that you glue the brick to and place on the wall. No damage to the existing, and you can move it easily. Single sheer will take at least 10 bricks, and making the labels out of PCB will be cheap as well.
