I would switch the living room furniture to where the dining table is and place the table under the stair area - it won't block the door to the kitchen like the couch is doing. (eta: I just notice er612 already suggested this arrangement). If you are renting, you might not be able to do this without permission, but get a hanging chandelier that plugs into the wall and swag it onto a hook over the table. Or get a floor lamp that arcs over the table. Chair next to door, sofa under window by tv, other sofa floating toward chair, tv by stairs.https://www.lampsplus.com/products/chandeliers/type_plug@in/ I came back to this thread to remove my comment of 3/14, but I couldn't find the thread, so I'll just apologize that it remains.

Thanks for the message. The structure can be altered this has already been discussed with my architect and done by neighbors. The premises is what we call a maisonette. In regards to swivel that could be done but I personally don’t find swivels nice and would give it a cheap look. To give you an idea what the property looks like from outside the balcony of my living room is circled in blue. The other 2 photos are my neighbors who have altered that balcony space. Also note that the window above the circled balcony was a balcony too which was closed up to a window. That was done by the previous owner.

Here's what I would do. Clear everything off the walls and remove the table & lamp that are by the entry and front window. Place the sofa like it is in your first two pictures. Empty the tall black bookcase, take it to the opposite wall and lay it on its side. Use it to put the TV on and decorate the open shelves with large decor items. If you feel it is too short, add some feet to it. Leave your current TV stand where it is in the foyer. Put the lamp on it and lay out your pictures on the carpet to see if any of them need to go above it. Here is a before and after of a redesign I did changing the usage of a black bookshelf. Sorry the lighting is not good, but she turned the shelf on its side and gave it a new look and purpose. You can do the same here. Before After

Just brainstorming here a bit. Can you wall mount the TV on an articulated arm in the corner by the rad? TV above rad, extra chair by window and door to closet (great reading area,) sofa on current TV wall. Then put the bed in the double window and inside mount black out shades that can roll all the way up in the daytime.
