Great location in the heart of Paris as others have noted.
Plenty of shops, metro stations & city sites to keep anyone happy.
The upper lofts are a bit tricky but certainly manageable.
Be sure to confirm amenities before arrival as we were surprised to find the washer/dryer were not working. A bit of a challenge as we packed planning to do laundry in the flat.
Otherwise, Paris is Paris: amazing in so many ways & Pauline’s apartment puts you in the center of it all!
