Marguerite was a great host! She was not available to let me in when I checked in but she had someone meet me and show me around the place. The place is very central, safe and close to public transit (6-7 min walking). Close to grocery stores, cafes, restaurants, parks, etc. The neighborhood is populated at all hours of the day and I felt safe walking around by myself.
I highly recommend Marguerite's apartment and would return the next time I'm in Paris.
