Our family of 4 had a lovely time in Paris! This place is as described - on the very northern edge of the Marais on a generally quiet street near Republique. It’s an old building with a central courtyard so there is a bit of general noise but nothing unusual. The area is very hip with lots of cafes, restaurants, shopping near.
The apartment has been done up with all modern needs. It does not have AC - I agree with another reviewers suggestion of a small fan because of the apartment’s layout. The hosts were great and happy to accommodate our request 2 single beds in the second bedroom instead of a double.
