We had a wonderful time staying at Catherine's flat. The flat has everything you need for a week in Paris. The location is fantastic: close to the Metro, restaurants, bakeries shops, and night life, and within walking distance to major attractions, including the Louvre and Notre Dame.
The area is fun, and lively at night with live jazz music often playing on the corner. However, the bedroom was very quiet and we slept well each night. Communication with was excellent and even though Catherine couldn't meet with us because she was away, she arranged for a friend to meet us. We would stay here again, given the chance.
