Marie's place was great for us. She communicated with us regularly and helped arrange access outside of her preferred hours - so appreciated! Marie's apartment is small but very comfy and with everything needed for a stay in a big place like Paris. It reflects a love of the arts and feels genuine. The neighborhood is multicultural with a healthy buzz, but quiets in the evening because it is a place of families. It is a good walk to the core of the city, but several Metro stops are nearby and the system is easy to use (and many locals helped us learn) and it will get you anywhere in the city. We weren't in Marie's apartment much over our 3 days, but did not lack for anything while there.
