Beautiful and comfortable apartment - pretty much exactly what we thought it would be when booking. We had a ton of fun just listening to the great CD collection (jazz, rock, Madonna) out of really nice tower speakers in the living room. The location seems like it would be busy based on how close it is to Sacre Coeur, but it's surprisingly insulated from the bustle there (nice trees out the window, on a slightly lower trafficked stairset from the main ones). There is a nice cafe to relax at and people watch down two flights on stairs from the apartment. Do keep in mind that this is one of the more elevated areas of Paris, so it is a significant walk uphill to get to the apartment.
