Great location, most things are within walking distance. A lot of good food options in the area. Lafayette is at 15 min walking, as well as Sacre-Coeur.
We stayed with 4 people, it is a bit small but the space is planned smart. Bathroom is big. Whoever is sleeping on the streetside can hear the sounds from outside easily and there is a draft by the window, but there is a thick curtain to stop some of it. Enough plugs for everyone's electronics. When its raining and you come in, it could get a bit messy.
Overall were very happy our stay and the communication with Marie.
