These are rooms that I like the look of:

I know that the best place for a piano (for its health) is against an interior wall. I’d try placing the couch facing the fireplace, with two chairs flanking it. Without knowing the dimensions of the room, I’m not sure there is enough space for a desk.

I really want to keep the piano and sofa where they are. The last picture show the spot I want to put a writing desk and chair. There’s enough room.

The piano looks awkward overlapping the windows. 2 chairs would be much better in that location.

Pianos must NOT be placed: Near a window. Windows can throw off heat, let cold air and warm air in, and are subject to changes in atmospheric conditions, temperature, and humidity from the outside, daily. These constant changes greatly cause your piano's tuning stability to suffer, and cause parts to swell or to shrink, which result in a poor mechanical condition and performance, whereas your piano's preservation suffers overall, at the very least.

I thought the room looked familiar. Reread the suggestions from last year. You were given some good ideas then

It was actually suggested to move the piano to the window area, so I want to keep it there. It was in an awkward space before. There’s not really adequate space for two chairs by the windows. It’s probably hard to tell from pictures.

Some option for your corner. As for blanket throw, pick some color from curtains and wall art above mantel.

That would look good. Thank you…
