We really enjoyed staying at Cyril's apartment - it was perfect for our family of four. We loved the location - very lively, and so many great places for food and drinks. We really appreciated being in an area focused on Parisians, not tourists (even though we very much are tourists!).
The apartment and courtyard are like the photos - lovely. Cyril was quite attentive to any questions we had, and we would recommend staying here any time.
Note: the steps are as noted by other reviewers, a bit tricky. I would not recommend them for families with young children, elderly, or anyone with mobility issues.
