When I get my own place I will so have spaces like this! I also know I will be terribly annoying as a go behind people after they've used these organized space and put things back that they've left out. I CANT HELP IT!
Love the multi-functional aspect of this room. It all looks so clean, neat and simple but you could use different areas of the room for different purposes with ease (e.g. TV, reading, coffee with friends).
