My family and I spent a wonderful week at Hadrien's place. It looks exactly like the photos, no surprises or disappointments. It's absolutely spotless. Very spacious and beautiful building. Very comfortable beds (which is important after a full day of walking in Paris!).
The location is perfect, really close to two metro lines, with a grocery store about a 30 second walk away, and ample bakeries, restaurants and shops in the area. We would stay here again without hesitation.
Something to consider if you have any mobility issues, it's 4 flights of stairs without a lift.
