I can't really tell what is going on with that larger second story window, but if you have the budget, I would change it out to match the style of all the other windows. Agree with ditching the too-small-to-be-attractive shutters, but I would beef up the trim around the windows in their place. Paint the downspouts to blend in with the siding. I think a porch across at least the original living space side would be nice, if you don't mind having the windows shaded (I would miss sun coming in my front windows). Because of the poor quality photo, I can't tell what that is in between the overgrown shrub and the front door. In any case those shrubs need to be replaced with a mix of evergreens, perennials, flowering shrubs that won't grow above the windowsills (unless you can keep up with pruning) - probably you can get help with a plan at a local nursery.

I like your existing layout but would place the console under the TV. I'm guessing since this is your only dining space, you'll want some flexiblity for additional seating. If so, I would look for a rectangular table. Not sure if this is an option but throwing it out there:

Paint walls solid white or very light color - get rid of wallpaper. I would not swap the toilet as older toilets were smaller. Replacing with a modern unit of any style will take up more room. The wall mounts don't save room and put stress on the wall. The shutters are gorgeous so keep! You simply cannot buy shutters with thin slats like that anymore. Remove the "secret" door and glass shower door. Simply use a thin white curtain. If the shower will not be used the space could be converted into a storage closet or combination of sink and shelves. Change floor tiles to white or very light color. Your sink is adorable and unique. If it is functional I would keep. The towel bar could be swapped with clear lucite or thin chrome bar. Remove wall basket. That space could be plain wall, a piece of artwork, or a bathroom towel holder (clear lucite or chrome). We remodeled our small home bath and are familiar with brightening up such rooms and maximizing space.

Ok I will try that measuring with tape. The curtains are going. Basically, I need to get rid of everything in the room but a few items. I hear ya on the sofa issue, the bigger I get on the sofa gets, the closer to the door. I want to add drapes from ceiling to floor, one on each side, of sofa like this picture. I also love the shades, but my windows are not deep. Its and old house (1942). I only have about 1 inch of depth for a shade.
