I've had the pleasure of using Airbnb for many different apartments in and around Paris, and Sonia's flat definitely ranks as one of the best. It's in a really fun part of the city close to the canal and tons of great food. The apartment itself is perfect for one to two people, very clean, and has an incredible view. The line 5 is right in front of the building, which is super convenient when arriving through Gare du Nord, and the Republique metro station is only a short walk away. Sonia herself was always pleasant to interact with and had lots of information throughout the flat to help anyone new to Paris navigate around the city.
