We were met by serenas girlfriend on arrival who was very welcoming and helpful. The apartment was a 15 min walk from gare du nord and a 2 min walk from a metro station and opposite a big supermarket which was ideal. The apartment was very comfortable and quirky. Although it was a little bit small, the 4 of us who stayed there were comfortable regardless. Serena was very easy to contact and replied straight away when asked any questions etc. I would recommend this place and would be happy to stay there again.
