Camille's place is great! It has a rustic charm, is really close to Pigalle metro station and only a 20 walk from Gare du Norde (if your arriving from the Eurostar). Camille didn't meet us in person, her friend Joy showed us around and helped carry my bag up (there are 5 flights of stairs...) She was very helpful and speaks great English. They were flexible with check-in and check-out. Montmartre is a busy area, especially on the weekend, so there is noise from the street. Other than that, if there a few sharing the bathroom is a tiny bit awkward as it's off the master bedroom (but the toilet is seperate). The view is great too!
