We stayed at Charles' apartment for three nights in mid Jan 2014. I emailed him a couple of days before we arrived and met Charles outside the apartment. He took us through all the essentials on arrival and left us with a map of the area and places to grab lunch, get some groceries and just hang out. Charles is very relaxed guy and has a great place. We loved his apartment and its location in Montmartre, walking distance from Gare du Nord and less than a 3 minute walk from nearest Metro station (Chateau Rouge). Charles place is plenty big enough for a couple. We would highly recommend staying here, a nice area to hang out and chill in Paris. Book now!
