We stayed with Valériane in May 2018 for four days. The apartment is small but cozy and located very close to the Gare du Nord (15 mins), Gare de l'Est (20 mins) and Monmatre with Metro stations close by. The apartment was clean and perfectly suitable for us, the neighorhood was very colorful but quiet.
We did not meet Valériane in person, but the pick up of the key at a local bakery (great croissants) was easy and without problems and we could check out flexibly on our last day, allowing us to leave our bagge in the apartment for one last trip of the city. Valériane was very friendly and communicated quickly via the AirBnB app.
I would highly recommend this place and her as a host and stay with her in Paris anytime again.
