You can opt for simple apartment living room design and decoration ideas if you have just moved to a new apartment where living room needs tweaks. I would mention here that many homeowners get too excited over DIY decoration and they sometimes end up overdoing everything. Try to be rational when you do living room interior yourself, do not over stuff it.
I suggest you to introduce some artificial or real indoor plants in the room to keep the air fresh and clean, also in apartment the rooms are very connected and there is less space, so leave some space spared and unused for allowing good air circulation within your area.
