Sea fans are a beautiful way to add natural decor, and the bamboo frame brings some of the warmth of your floor up to eye level.

An antique mirror in whatever finish you like would give the room some personality.

This little shelf and the live greenery caught my eye.

Target has this abstract West Elm style rug that has a warm, modern vibe.

You might wait until you settle on a rug before you choose pillows. Nice place!

First, do you own or rent the condo -- are there any rules prohibiting you from painting any part of it? If renting, do you really want to make permanent costly changes even if you're permitted to do so?

The gray doors and trim actually go well with your black countertop and furnishings and don't clash w/the brown sofa. If you paint any trim, you'll probably need to paint all the trim ... and probably the doors, too. This would be expensive to have done professionally and any mistakes could cause a renter to lose their deposit. Consider leaving the trim and doors as is and, if permitted by whatever condo rules with which you must abide, repaint the walls instead.

If you do decide to paint the trim white, Benjamin Moore makes a stark, true decorator's white -- likely a better choice than the off whites, many of which can have a pink or yellow hue to them.

The kitchen walls -- backsplash and over the overhead cabinets, are a distinctly separate space than the rest of the condo. White subway tile backsplash is worth considering but is more costly than painting -- something to consider, especially if you're renting.

With bold black countertops, you might consider painting all the kitchen walls your favorite bold bright color. Then you could paint your dining table the same color, or perhaps just the top that color and the rest of the table black (as many of your furnishings are).

Behind your stovetop on the wall between it and the hood, you should probably add a panel designed for that space -- easily cleanable and flame resistant. Stainless steel would be best -- the white over metal ones can more readily show scratches and/or stains.

In such a small living room area, a rug is optional -- the seating area is pretty well defined. It wouldn't hurt to walk through a few stores and see what's available in a size the same width as your sofa and long enough to extend from beneath the front legs of your sofa to beneath the front of the furnishings opposite the sofa. Wouldn't want a room sized rug -- even if it didn't interfere with opening the door, extending it beyond the sofa into the traffic area from front door to kitchen/dining area would be counterproductive to the purpose of an area rug for a living room.-- to define a sitting space.

With little seating, a single throw pillow with your favorite colors would suffice.

Plain, then -- metal (think document frames) for art would work with what you have or you could choose something without a frame -- perhaps pressed metal art.

I googled pressed metal wall art trees images

https://www.google.com/search?biw=1366&bih=650&tbm=isch&sa=1&ei=0I1QWumOII2-zgKtnozgCQ&q=images+pressed+metal+wall+art+trees&oq=images+pressed+metal+wall+art+trees&gs_l=psy-ab.3...6401.7143.0.7285.6.6.0.0.0.0.45.259.6.6.0....0...1c.1.64.psy-ab..0.0.0....0.5INBPx3xz0c

You could replace trees w/any object or subject that reflects your interest to see what might be available. What interest you? Mountains? Beach? Hunting? Biking? Wildlife? Music? Then, if you decide that metal art is something that interests you, change "images" to "shopping" to begin your search in earnest.

Modern wall shelving, including but not limited to box shelving, can be both decorative and useful.

Update us -- let us know what you decide to do and post pics.

First I would get the layout corrected. Size of rug will be determined once furniture is in place. Will the tall bookcase fit to the left of the windows with the desk at a right angle to it on long wall? TV where bookcase is now with loveseat facing it. Pull dining table over so that it is centered on kitchen opening. Try these changes & post pictures

It's funny, first I thought no, don't paint the trim! Which, I might add, looks like darkwood to me, which I like, and gives the place a bit of a sense of history. However, I looked up some silver sage rooms and I must say it looks born to live with with white. For example

So now I'm in should she/shouldn't she mode. I think you probably should, depending on what that wood is.

I very much like the rug Kim posted as the neutrals blend well and the colours are both soft and bright. I could see that not only working, but being lovely to work from for other colour in the room.

Final brief point from me right now -- can you pull the sofa away from the wall far enough to have a small side table on each side? It looks like it's scared and clinging to its mama. Make it independent.

I agree with jck910 that a different LR layout would be interesting to see. Another option would be to put the tv on the buffet cabinet and move the tv stand to another room for storage. You could try the loveseat where you currently have the desk & bookcase and slide the buffet down to center in front of the loveseat. Then put the desk in front of the window and the bookcase next to the tv to create an entertainment center.

The dinette set is centered under the chandelier, correct? It looks like if you try to center it on the kitchen, it will block traffic flow to the other parts of the condo.

I wouldn't install a white backsplash, because it might be too contrasting with the other elements in the kitchen. I had the same thoughts as Rina about painting the woodwork. Sure it would be pretty in white, but it also looks nice as is.

I ran across another decorative branch. Beautiful!
