@aa To add to @sku_b’s great advice, try keeping everything you have and not buy anything for at least 6 months. This gives you a chance to figure out layouts and what you might want or need. Sometimes a simple re-arrangement of furniture will suffice and you don’t need to purchase anything else.
On the flip side, depending how much freedom you have to paint and customize the unit, it gives you a chance to come up with ideas for how you want your place to look. Then you need not worry about buying something that doesn’t fit your vision and taste down the road.
