Anne-Laure provided us with all necessary information (not personally but through email) about how to get to the apartment. It's a really small apartment which is suitable for short stay. It's quite close to city center (25 minute walk or a few metro stops).
There are some disadvantages that we experienced during our stay (but it's not crucial objectively) but might be helpful for some people:
- view from windows to the walls;
- there is no door (just a shower curtain) isolating toilet from kitchen and room, so that you can't feel privacy using it ;
- bed linen was covered by something that looked like cat hair;

In spite of these minor issues we had a good stay in Paris
