We had a lovely stay at Francois' apartment. He was very helpful in arranging a friend to check us in and out and was very flexible (we checked in late on Friday, and Francois kindly allowed me to check out late on the Monday). The apartment itself is as beautiful, bright and typically Parisian. The area is extremely convenient being just a 15 minute walk from Gare du Nord and there are lots of really cool bars, restaurants and shops. Would highly recommend and would definitely stay there again.
