Me and my friend had a most amazing first time in Paris staying at Joanas apartment. It's somewhat smaller that the pictures, but all the more inviting. Its location is quite central, and we had no problems getting to a lot of our destinations by foot, but it's still not in a specially touristic area. As a matter of fact, the charm of the apartment and the neighborhood is such, that for the ten days we stayed, we actually felt like we "lived" in Paris.
As far as other practicalities go, there is a huge grocery store right outside, as well as a butcher and a bakery across the street.
Not to mention that all along our wonderful host Joana was communicative and helpful.
Certainly a place to recommend!
