We enjoyed staying at Marguerite's apartment. She was sweet, helpful and had good communication. The bed was comfortable and warm with good memory foam pillows. The bedroom is large enough and has a desk and large window that didn't always stay closed.
The kitchen and bathroom were not particularly tidy or clean, but they were quite usable and did not feel dirty. This apartment is shared by students, but we didn't have any issues with noise or shared spaces. Both kitchen and bathroom had quality equipment (the shower in particular was really nice).
The location is good, barely 30 seconds walk to the metro Colonel Fabien, and there are some restaurants nearby (our favourite was Tien Hiang, serving vegetarian Asian food). It is also walking distance to gare du nord, which was great for our early flight from beauvais.
We would certainly be happy to return, this room is great value and Marguerite was lovely.
