Cecile’s place was great for my sister and I. It was clean and cozy. The only two things of note would be that there is definitely a need to use the metro to get to tourist attractions, but the metro (even as someone who knows no french) is incredibly easy to use. The city is so big this is probably necessary anywhere you stay. The other thing to note would be that the key is given to you by a Keycafe lockbox inside a cafe- so make sure your checkin/ checkout times correspond to when this cafe is open, and if they don’t, contact Cecile.
She also gave good instructions on how to get to her place from where I flew into the city, which was helpful (along with asking some kind folks for help along the way)!
