As chookchook said in her recommendation about painting, put a drop cloth on the floor. Get a very safe ladder. remove the lightbulbs, and cover the outlets. Turn off the electricity to the chandelier. Then spray it with a mild cleaner (I use one I found at Target that's basically water with vinegar, until it's dripping wet. Start at the bottom and work your way up, so you don't have dirty spray dripping on the bottom of the chandelier.Work your way up and down until the dripping spray is clean. The chandelier may be gorgeous and expensive, but it seems totally out of place in the architecture of the room--more at home in a chalet than a sunny room with a window wall. I would probably try to find a way to get it removed, and sell it to someone who appreciated it better than I.

Thanks everyone for the warnings. Honestly I had not thought that could be possible so just in case I'll gear up with a mask to avoid inhaling any of it. I will still need to remove it, but from what I read the problem with asbestos is if you sand it and make it into breathable particles, so ripping it out should be ok. I've looked up in youtubr and there seems to be a tool called mastic remover that you can put on your floor sander and it would scratch the surface removing any of that stuff.

Not wanting to build anything just make this fireplace look nicer and not so much of an eye sore... cheap and DIY as it's a temporary house!

Even with the present layout , I would have tried to make the walkways around the back of the couches . If you are changing the couch , it might be a bit easier , but you'll have to select couches that not only look good , but are the right lengths so you can get around them -- not too wide . With the benefit of hindsight , I suspect the TV , or even a smaller one , above the fire would have been better -- keeps the furniture all focused on 1 thing , so that way you could have had couches either making a hallway , or right back against the walls . Right now you are trying to do everything , with 2 focuses , and there isn't quite the space to do that . IF you move the TV , get an artwork for that wall -- not only shows some colour , some of your personality , and maybe even hide some holes and cords haha .
