We enjoyed our stay at Olivier and Mathieu 's place. The appartment was as described, clean and conveniently placed in the Marais aera. Olivier and Mathieu are very dicreet and we had the appartment mostly for ourselves. Lots of liftle cafes and restaurants around in the vicinity. Nice place to stay for 3 or 4 days. Our thanks to Mathieu who welcomed us and helped us for the flight bookings!!
