Catherine's apartment is very cozy, clean, and well located. We were able to walk or take a quick metro trip to all the places we had on our itinerary. The historic neighborhood is fun and lively with lots of great restaurants and patisseries. We were especially pleased that the bedroom was so quiet, and we enjoyed waking up in the morning to the beautiful courtyard view. The apartment and the neighborhood seem very safe -- we had no concerns about coming home late at night. Catherine responded promptly to any questions we had, and we will definitely book here the next time we come to Paris.
