We stayed in Caroline’s place for 10 days and the apartment is lovely. Great communication, someone waited for us for the check/in, we did self check-out. We had a well-equipped kitchen and everything was clean. It is also close to the metro (5mins to line 4/ Barbes) and there’s and Aldi shop in the proximity. Beds and the sofa are really comfortable. The only issue is the neighborhood: nothing really happened to us, but there is an unpleasant atmosphere- men of color staying on the streets till late at night, smoking stuff and drinking, two homeless guys living in the corner of the street. If you are a girl traveling solo I wouldn’t really recommend it. Otherwise if you don’t plan to spend too much time in the neighborhood and you just go there to sleep it is fine. It is really close to Montmartre and the metro is making every touristic spot in Paris very accessible.
