Roomtour - ich gestalte meine Wohnung um

Here's what my apartment looked like before the makeover. Do you have any ideas for the rooms? I have some initial thoughts, but I'm still missing some really innovative solutions. How can I make the rooms cozier, how can I add more personality? Right now, everything feels too basic. My apartment has maybe four cool pieces of furniture; the rest is just so-so. We need to change that! Feel free to follow along if you'd like to be part of it.
