Christina's apartment was perfect! Pretty sure it is premier real estate in Paris :)
It was so cosy, I didn't want to go out at all but its not my first time in Paris.
*55 sqm and every inch of it is usable, it is a square shape which meant it felt bigger than it is;
*Close to two subway stations, really easy to get around;
*A block from Luxembourg gardens which was perfect for my morning runs, it felt like my own backyard;
*All the bathroom and kitchen amenities are pretty new and renovated using top quality material;
*Noise free, you cannot hear the sirens;
*There is no clutter in the apartment, so it is extremely comfortable;
* Warm, I stayed during peak of winter when it snowed and I didn't have to use the heaters at all;
* Small block with only two on each floor, a good sense of privacy;
* Lifts, no need to carry your luggage up the steps;
* Yes, the markets outside were fantastic too.
I could not fault it. C'est tout!!! ;)
