Apartments demand a special interior decorating touch. You must take away the feeling of an apartment by decorating your space without running afoul of the landlord.
Most rentals are often faced with the same lighting fixtures, wall colors, carpet, flooring and cupboards. You can express your creative idea by add in touches that look permanent but actually are not.
Since your landlord might not even let you paint, you can apply large wall stickers, such as poppies that reach from a floor to ceiling to add color to bland walls while giving your space a hand painted effect.
Maybe you need to ask permission to hang up curtains for a homey touch. Many landlords will ask that the lining of the curtains be white so it matches the rest of the window treatments in the building.
One simple thing that adds a huge change for overall appearance is making a statement with furniture. You should spend a little more money to get pieces with style. Look at the overall area building design to take the idea of your furniture and decorating style.
