Reddit mentions of Casual Home Kitchen Island with Solid American Hardwood Top, White

Crappy Paint Mockup of how I'd live as a single young person in this space: https://imgur.com/a/2PCm7bA (If you are a couple and need TWO sets of multiple monitors, this wouldn't be sufficient, but I can't tell how many computers you need running at once here.)

I agree that your first stop should probably be ikea. They'll have good-enough desks that will look pretty good and work pretty well for a solid decade. You might look into an adjustable height desk so you can play with your optimal height. Or with a standard fixed desk, I agree on the previous comment that you probably want an L-shape.

Why do you hate couches? When I was in a small apartment, I got a "chair and a half" -- it easily fit two people that were happy to be close together. (It had a storage ottoman (more seating!) and folded out into a twin bed. It was the best.) You do need SOME nice comfy seating to curl up in. Ikea also has plenty of chairs. You do want at least two and something to put drinks and books down on nearby. Could be two chairs and an end table, or a coffee table, or a rigid tray on an ottoman.

Bookshelves. A nice freestanding ladder shelf would be good. Tons of styles, like https://www.amazon.com/SONGMICS-Bookcase-Bathroom-Furniture-ULLS44X/dp/B074X7WT6D


Here is a storage ottoman that is easily moved from place to place. Great to have a few around to unfold and put away as needs change. Less expensive than the fancy upholstered kind. You can rest your legs on it from a chair and then use it as extra seating when you have people over. https://www.amazon.com/SONGMICS-ULSF47K-Foldable-Space-Saving-Capacity/dp/B07JQ22YYS

The desk chairs look really ... young. Hard to advise there, though. If you spend significant time on the computer, I think it's better to prioritize function over form, or you WILL have body problems down the road. Get nicer looking chairs if you can. If you can't and these are working great for your body... eh. Make everything else look nice. You probably only need one desk chair, unless there's two of you with two PCs?

You may want a kitchen island to give you more counter space and storage space. You desperately need counter space. Here is an inexpensive one but they are all over the map for style. https://www.amazon.com/Casual-Home-Kitchen-American-Hardwood/dp/B00ROX6VRW/

You probably also want some shelves between the dishwasher and the balcony. Shallow for just glassware or deeper for holding actual dishes. Just give yourself a wide path between that and any island that divides the kitchen from the living.

I am thinking you don't need a dining table and chairs, so make your living space do dining duty. Or get a kitchen island unit that includes a bar and put barstools there.

Don't forget lamps. Good lighting will make this a home, and those will travel with you.
