Happy bunny up and running again.
Thank you for all your concerns, I am OK now. And don't get me wrong - I am not the ungrateful bitch who expects to be treated like a queen when travelling on business. I think I was just grossly deceived by the serviced apartment's website, that's all.
Anyway, I have now overcome the initial shock and horror and am starting to enjoy my stay. I am typing away in my office now. The people seem nice and the view outside the window is great. I love Paris :)
