Surprised at how hugely over-the-top touristy Montematre was. (However, as I was there as a tourist I can’t really complain…) It is a very quaint in a cobblestone-y, windy-street way.
Sacré-Cœur is beautiful, once you run the gauntlet of the souvenir sellers, buskers, girls pretending to be deaf/mute. Great view of Paris and an amazing building.
Preferred the lower parts near Pigalle where it felt more like the rest of Paris.
