Without seeing a plan and knowing sizes I will hazard to say that the wall space between the two windows in the last photo is seemingly the most logical spot for the bed. This placement might now allow for nightstands as one leaf of the closet door would probably bang into a nightstand on that side. It seems to be a very large space. You might be able to accommodate a seating group between the bed and the office space alcove. The alcove where the bed is shown in the photo might lend itself to a window seat and perhaps narrow cases or shelving for books.

Thanks it is an exciting time for us! She is so happy:) here are some Images from my sons wedding it was so pretty...my daughter in law found this women that rents out all these vintage old pieces and creates beautiful centerpieces and than the florist added flowers and succulents..it was something I had never seen before....hard to top for sure!

It's so pretty! I don't know if there is enough room to do this, but I might look for solid draperies the same color as the walls and center the bed on the window. Or at least move it away from the wall. Just kind of ignore the window. It will be difficult for guests to enter and exit the bed and for making it/changing linens. I'd look at art shows, galleries, thrift or consignment stores for art you like. You don't need much!

I pushed the twin bed in my office up against the walls, then had a custom slipcover for the bed and large bolsters all along the length to match. I also had two large square pillow covers made to add some contrast. Now it is a tailored daybed/sofa look instead of a twin bed.
