It doesn’t really matter how small your apartment is, you can always get a nice space with modern and unique decoration.
In a small apartment decoration it is very important to emphasize the color of your walls. White or clear walls, as well as windows will help you to give that sense of bigger space. No matter the room we are talking about, clear colors will be a basic feature in any small space you have: living room, dining room, bedroom, bathroom, laundry room, kitchen, etc.
If the distance between the floor and the roof is big enough, you can think about building a mezzanine, that can be used as a home office, or an extra bedroom.
When you choose your furniture, make sure to pick big ones. If you fill your small space with small furniture, it will result in the smallest space ever! You have to try to select a big piece of furniture that suits your space, and then you can pick a pair of small accessories.
