Gregory was a joy to deal with - very friendly, left personal recommendations in a file for guests - very accommodating. The flat itself is in an ideal location. It's easy to get to by metro, especially from Gare du Nord with Richard Lenoir being on a direct line. The flat itself is very nice. It would be great for a family. With one toilet on the ground floor, those in the basement room have to get used to some tricky but fun steps if they need to go during the night. We really enjoyed staying in Gregory's flat and rather than travelling by metro, we walked to Bastille, République, walked back from Galeries Lafayette past the Louvre, Notre Dame through the Marais Canal St Martin, etc. Great for if you like exploring on foot.
