We had a great 11 days at Simo's flat near Rue du Montorguiel, surrounded by shops and cafes. It fit our needs quite well, and it is in a great location--within walkable distance to many sites in the heart of the city and along the river, and close to east-west metro lines, north-south metro lines, and the RER to Charles de Gaulle airport.
Since Simo was out of town, Clement oriented us to the area, the flat, and the electronics. Fortunately, Clement was quite reliable, despite our train delays and poor phone service en route.
We would stay again and would recommend this flat to others. Thanks, Simo and Clement!
