Pros: awesome balcony (view was incredible!) and well equipped kitchen. Location was near a good metro line (4) that got to the main sights quickly. Bed was comfy, though we certainly were exhausted from walking around Paris all day :) Right next to Sacre Coeur!
Cons: somewhat rough/sketchy area (did not impact quality of the space/ quiet at night), bathroom was a little interesting and the towels desperately need replaced. No AC which got a little warm our last night, but this is probably customary in France.
Overall a nice home base for our time in Paris! Very quiet building, just a few things need replaced for a five star stay. Thanks Martine!
