It's a rental so buy something that you can take with you that will work in your next home. Just stay with green and white. You may not be able to change the panels, but you could add to them where it can't be seen from the outside. Add white to the outer side of the blue panels. Then get a navy and white throw pillow for the accent on the white sofa.

You can put the TV over the fireplace, not the best situation but the way the room lays out it is the only logical place to put it. If you could you should add one additional layer on your mantel that could extend it out another 4" to deflect the radiant coming from the fireplace. I would also mount it on a slimline mounting bracket and have the bottom of the TV no further than 4" above the mantle. Ideally you want the TV to be in as straight a line as possible with your eyes. You don't want to look up too high at the TV, it's like being at a sports bar. Also if you can snake up the power and the HDMI from the cable there is a box they make that has both in one so it makes for a very clean installation.

Thanks Carole, yes we are very keen to knock out that wall - I have to be restrained from bringing the sledgehammer inside until we get a proper load-bearing beam organised! Once thats done and the books are off the floor and on the wall opposite we will have to think of rearranging this space - I still like it split up by a couch, but perhaps we could put a larger dining table in the new space.

Here's an alternative to a recliner that you may not have considered. It is a snuggle chair with matching Ottoman. It swivels too. Available from Plush Sofas. I love ours... So relaxing and there is room for two adults. Available in leather or lots of other fabrics too. I took this photo of the shop display one before we bought ours...
