My sister and I had a wonderful extended weekend in December in Julien’s beautiful apartment. The apartment is beautifully decorated, cozy and well equipped and very clean. We felt at home immediately. Julien is a flexible and very accomodating host, and was fast at replying. Check in/out was perfect. Location in walking distance to the charming Montmartre and Sacre ceur, and also an easy walk from Gare du Nord. The only thing I would say to beware of is that I would not feel 100% at ease walking through the neighborhood late at night if I were a solo female traveller. Other than that, I highly recommend this AirBnB
