Antoine is a pleasant person who was on location to greet us and made sure we were comfortable during our stay. The flat is fantastically situated in the heart of Montmartre, next to a metro station with lots of cafés and restaurants around.
It is on the fifth (last) floor (with an elevator), well isolated to prevent from getting too warm during very hot days (we were there during a heatwave).
We recommend without hesitation Antoine's flat to discover Paris for a few days!
