We (family of 4 with two teenage girls) loved this apartment. It is even bigger than you expect from the pictures.
The apartment is perfectly located to the main tourist sights and to Rue St Jean, a very long street where you can get everything (supermarket, pharmacy, lots of shops and restaurants).
André was a superb host. He was extremely helpful when we had a family emergency (thanks again, André).
All in all we had a great stay and would definitely be back.
