The apartment is located in a wonderful, residential neighborhood of Paris. It's a 5 minute walk to the 12 Metro line, 10 minute walk to the 8 Metro line, and multiple bus lines are all around. The neighborhood is quintessential Paris, with multiple boulangeries, brasseries, restaurants, and shops; it's hard to pick the favorite of each but being so close makes it easy to explore and find out. Multiple grocery stores within 5-10 minutes.
The apartment itself is super cozy, located on the ground floor of an classic Parisian building. The rooms are comfortable and everything one needs is available. One thing to keep in mind for North American guests: the water heater is small compared to what one might be used to back home and the kitchen sink is the biggest hot water hog, so time your dishwashing and showers accordingly.
Francois-Marie is super-responsive to any questions, but otherwise leaves you be, which is the ideal Airbnb experience in my opinion. I highly recommend this place!
