Loved my stay at Joachim's flat. it's in a very nice area, close to everything you need: metro, nice bars and cafes, supermarkets, Gare du Nord. The apartment is on the fifth floor (no elevator) with a nice view from the balcony. Quiet at night and very clean. The check in was super easy and Joachim always easy to reach and friendly. Will definitely book again next time I go to Paris!
