We are newbie Americans who had never visited Paris. We had no idea what arrondissements to look at staying in, what to be close to, etc. Laurence's place was perfect! The pictures don't do it justice. The apartment is right in the middle of the action in Montmartre (or, some of the action, because it's so big). It is conveniently close to dozens and dozens of restaurants, bakeries, and coffee shops. It is also right next to a metro station, and just down the hill, there's another that will get you on a different line. It's not too far from Gare du Nord, so it's easy to get to and from the airport or to travel outside the country.
The apartment is beautiful and filled with sunlight. It has several windows which we would open right when we got back at night to let the cool air in and hear the action down below. The bathroom and kitchen are nice as well. Would definitely recommend! The couch is also a futon that I slept on comfortably for a week.
