My friends told me I should stay in Le Marais for my first trip to Paris, and Pierre's place made me feel like I lived in the neighborhood. Pierre was out of town while I was staying in his apartment, but he was very communicative and helpful from start to finish. He even provided a list of nearby establishments to check out, which was really helpful during my first couple of days.
The apartment itself has a lot of character. It's full of books, media, decor, and all sorts of odds and ends that remind you why you chose an Airbnb over some random hotel room. The location was also fantastic - there are quite a few bistros, brassieres, and boulangeries within very short walking distance. It's one of those neighborhoods where you can just wander endlessly through all the narrow streets until you find something that catches your eye.
All in all a great stay!
