Congrats. What furnishings will you be bringing with you? This really cute condo is small enough that a room rug is unnecessary -- a room sized rug would even visually shrink and warm/heat the space. That doesn't mean you couldn't put a 3'x5' rug beneath a chair and ottoman. I grew up in a kitchen with walls and (metal) cabinets painted pale yellow, with only slightly darker yellow window trim and recently have been seriously considering repainting my own kitchen two shades of the same color ... perhaps blue; perhaps yellow. Perhaps you could use two shades of your own favorite color for your kitchen. Are you planning to leave the wallpaper trim tape atop the wall? If so, you might take that color into consideration as you choose your paint colors. Is that the back of a microwave I see at the peninsula? If you're not going to use that bar as a bar (wouldn't), consider removing it and perhaps adding a rectangle box shelf (with a back to it) the top of that pony wall so you'll have a shelf for your microwave and/or toaster oven without them sitting on your countertop. You'd probably have room to set S&P and sugar bowl and napkin holder on the countertop beneath the overhang of a box shelf and still be able to use the countertop space in front of that for meal prep. Instead of just a sideboard w/art beside the kitchen, consider a full 6' high china cabinet -- saving your kitchen cabinet space for other items. Having solid doors below give you storage for things you don't want to display; having glass doors above enables you to display some of your dishes. The open shelves in the middle enable you to place items there you need to access regularly such as decorative canisters. If your china cabinet and dining table/chairs are wood with a medium finish, that will visually warm your space. For end tables and bed side tables, consider 2drawer filing cabinets made of the same wood as your dining set. Not only will your "tables" do double duty as storage for documents you need to keep, the drawers are deep enough for purses and/or camera equipment and/or other hobby items. Some have a third shallow drawer above the two file drawers and some even have locks. https://www.google.com/search?q=two+drawer+wood+file+cabinets&source=lnms&tbm=isch&sa=X&ved=0ahUKEwjbupSi_7PaAhWLVN8KHfHRBxQQ_AUICygC&biw=1366&bih=650

I’m not a pro... Congratulations on your new home! I think the right shade of white or off-white will make a huge difference. After painting, rugs will bring it all together for you. If possible, removing the valances would be a good idea.

The current layout creates a hallway through the living room, and doesn't allow you to enjoy the view. I would wall mount the TV to the right of the windows, or put it on a slim console. That heavy console needs to go, and probably the desk. The couch looks fine, if it's comfortable. I would get rattan side chairs. The tile looks to be in good shape, so you could get a sisal rug or a colorful indoor/outdoor one. Do you plan to rent this place out? If so, that needs to be a primary consideration, because renters have a way of destroying things.

Looks very nice. I’d go with light grey sofa and I would add a rug that has a design even if it’s in muted shades.
