Great stay and excellent location in central Paris close to everything!
My only feedback would be to ensure pictures and description match the description. Flat is on the ground floor (no Eiffel tower view - perhaps the upper flats have this) and courtyard is not like the pictures it is just plants with no chairs and tables to sit. Due to it being on the ground floor and facing the courtyard, apartment is quite dark even during the day and is susceptible noise of people going in and out of their flats and noise around the complex. Not recommended for someone who values privacy as again it is open to the courtyard and people frequently come in and out of the other flats - draping is sufficient but not ideal to have all the time due to the little availability of daylight in the flat.
