Wonderful, huge appartment in the 20est arrondissement. It's vintage, it's old, it has a great atmosphere. With some small improvements (bathroom and wifi for example) this would be our secret tip to friends visiting Paris.
We used the appartment as a base to see some city highlights with the kids, but the neighborhood itself has it's charms too like nearby Père Lachaise cemetery, an oasis of silence and melancholy. Bakery Banette was a good tip, just like Rue Saint-Blaise and Rue des Haies. Communication was fast and accurate anyway.
Thanks Georges (and Juliette)
