I really enjoyed staying at Marie's place, its in a real bustling neighborhood and literally right across the street from the Metro station, there are bakeries, supermarkets, a laundromat and anything else you can want! If you want to stay in a neighborhood that is alive, eclectic and not too stuffy then this is the place to stay for you. It is real Paris, not filled with all the touristy traps or expensive shops.
The metro is across the street (Line 11) and you can get to many places like the Pompidu, Louvre and even up to Sacré-Cœur within minutes. (download the Paris metro app on your phone)
Marie's place is quaint, would be great for two people, but It was only me for a week, its your whole apartment, great shower, good water pressure, comfortable bed, everything was clean. It is an old Parisian apartment so you are living like the Parisians do. There is 4 floors of stairs to climb every time you come up and down so if you do not like walking stairs or have mobility issues, there is no elevator. Not an issue for me, but may be for some.
I never got to meet Marie in person, she was out of town but we communicated quickly when I could not figure out the wi-fi password. Her friend Caroliny got me into the place and she was very communicative as well. I felt right at home and part of the neighborhood. I ended up cooking basically everyday, went to the local supermarket and saved tons of money instead of eating out! I would stay at Marie's place again for sure, honestly did not want to leave!! Bojour!
