Everything is exactly how it is listed on AirBnb and Sylvia is an lovely host, very​ easy going and she has cool apartment. You can walk to Gard Du Nord in 15-20 mins, otherwise it is a short hop on the metro. I was not sure about neighbourhood at first but it was safe after all but I did only stay two nights. You have to pass Sylvia's room to get to guest room and again this was no problem at all. I did get woken up early one morning by some workmen but I imagine this could have being a one off situation. I would definitely recommend this place to book, especially for the price.
