Maxim was really helpful - he was very responsive to emails and texts even though we booked at the last minute, always answering very promptly. The apartment is in a fantastic location, on a picturesque, tiny island right in the heart of Paris, a couple of minutes' walk from Notre Dame, with fantastic cafes and restaurants on every corner. We stayed in February and the flat was heated very well, and the light coming in from the courtyard is lovely. We'd definitely recommend Maxim's apartment to anyone staying the weekend in Paris.
