Beautiful apartment in an amazing location, two minutes down the hill to Montmartre village and two minutes up the hill to Sacre Coeur. You can see big tour groups passing the window, but the apartment is tranquil. Pierre Emmauel was a great host, always responding quickly to questions and liaising with the concierge (who takes care of on-the-ground practical issues, including check-in). The big industrial action hit half-way through our stay, meaning the metro near the apartment stopped running, but the apartment was a lovely place to be stranded and with buses and walking it was nice to see a bit more of Paris.
