I had a lovely stay at Mireille’s place. Although we did not get to meet Mireille, her husband welcomed us and provided a quick tour. The apartment actually looks better than the photos and has plenty of space for 2 people. The neighborhood felt safe even when walking around at night. It is near a police station which added a sense of comfort as well. As others have mentioned, it is a short walk to the Catacombs and the metro. If you would like to get to other attractions and do not mind using public transportation, this place is perfect. I have to say that it was nice to come back to the apartment after long days of exploring Paris.
