The apartment is located in the Marais, perfectly situated close to attractions. It was a 15 minute walk to Notre Dame and about 20 to the Louvre. Metro stops were also convenient, with options for multiple lines.
The apartment itself is tiny, but so well decorated and organized that you don't even notice. You have to walk up one set of stairs, but it's quick. The window opens to a central courtyard that faces other apartments. You don't have a view, but you don't spend much time in the room while in Paris. The nights were quiet and the bed ok (it makes noise everytime you move).
The air conditioner is a portable unit, but it does a great job at cooling the apartment down quickly.
We would stay here again in a heart beat.
