Montmartre is an amazing area. Loris Airbnb is small, quiet and close to the station and many bars and restaurants. It's very comfortable with good shower and heating.
There is a slight quirk with the door that Loris will provide instructions for, but ideally it gets fixed as I was stuck outside the place for 20 mins trying to get the door to work.
Other than that 5/5 I would stay again and recommend.
