Marie is one of the most friendly and welcoming hosts I've ever met! She was super responsive during the booking process and gave me sufficient information about the place and how to get there.
The place is in a nice residential area with easy access to metros and buses. If you like walking, you can actually walk to most of the major attractions (e.g., Louvre, d'orsay, Eiffel tower, etc), which I actually did and enjoyed. The place is what I've always pictured an ideal apartment in Paris: small, cozy, rooftop, and felt like home. Plus, you also get the health benefit of walking up ~100 steps twice a day : )
