We really liked the way Isaacs appartment is decorated, the fact that it's cleary his own house makes it authentic and still, he made his bed look like a hotel bed.
All in all we did have to adjust to the neighbourhood, which is not touristic at all. In the end we were happy we were here and nowhere else. We loved Parc La Vilette!.
You have to know: the appartment is on the 10th floor.
We haven't actually met Isaac but he was very quick in his reactions to our questions, as if he was there! Even when it was late.
The cafe where you can pick up the keys is also very much recommended for it's food and view over the water... !
