Doesn't get any better than this. Spacious, clean apartment in Montmartre, perhaps the most beautiful neighborhood in Paris. And not to mention two rooftop patios that literally overlook the entire city! You name the famous site, there's a good chance you'll have a view. Also, you have the Sacre Coeur right in your backyard, and a Metro stop only two blocks away. Incredibly easy access to anywhere you want to explore.
While my wife and I never got a chance to meet Martine, she was incredibly gracious and communicative with giving us apartment access, along with any help we needed throughout our five-night stay. I cannot recommend this place highly enough. By far my favorite Airbnb experience to date!
