Christine’s apartment in Paris is in a great location, within a few blocks of the metro and on a street full of markets, bakeries and within walking distance of Sacre Coeur. While Rue Lagille is not the prettiest street in Paris it is a pretty safe area. Le Championnet, across from the entrance to the metro, is a great spot to eat or have a glass of wine.
The only thing I think should be mentioned is the stairs going to the apartment. It’s a very narrow, steep, twisting staircase and some of the vertical rails on the banister are not attached so it’s very difficult to carry luggage up to the very top floor. Also, while we were there, there was no lighting in the entrance or the stairwell so coming in at night is scary.
