Great location, just a couple of minutes walk from Gare du Nord and about 10 min walk to Montmartre/ Sacre Coeur. To get to the flat you go through a large door from the main street into a quiet courtyard. Great host, fantastic communication, super easy check in. Really good boulangerie down the road for morning croissants and pains aux chocolats - Grain O (turn left out of the flat). The flat worked really well for us (3 adults, 5 children). It’s a bit more tatty than the photos and the mezzanine bedroom is accessed by an open riser staircase with quite a dangerous gap at the top. I wouldn’t have felt comfortable letting kids stay up there, and it wouldn’t be suitable for ‘older’ guests. My husband and I took the space as somewhere to crash and used our kids room downstairs to dress etc.
