It's bloody hard to get rid of a lot of stuff. I had a great leather sofa, about 15-20 years old (inherited from my grandparents) still in great condition, but I couldn't get rid of it at any price and none of the charity shops took it because it was missing some fire hazard label (sigh...). Same with almost everything: I sold my 2-year old £1,200 mattress for £50 (and I had to practically beg to guy to take it, because it would have been a complete shame to chuck it). Washing machine, fridge, all the "little stuff" (cutlery, books, DVDs, what-have-you). I ended up putting a lot outside "free stuff" and that got rid of a lot.
Actually the only things I managed to sell was an IKEA sleeping sofa and an IKEA dinner table set.
That said, since then I found that actually finding good stuff isn't always easy.
The rest of Paris is pretty "European city" and maybe I'm not tuned into the differences, but it seemed quite like Munich, Rome, or Barcelona except for the language, etc.
