Yannick was a lovely man, he was so welcoming and friendly. He had breakfast for us twice! Showed us to the room, which was quaint and cosy. But I wouldn't recommend the room if you taller than 5 ft 7. This is because the room is basically up the attic, and I'm 5 ft 6, and couldn't stand up straight half the time. Aside from the height issue, the room is actually very big, and the bed very comfortable. The house is also very conveniently located, if you're taking a train into Paris, this house is only 4 stops away on the metro from Gare Du Nord, so it's super convenient.
Thanks Yannick, you were lovely!
