Matthieu was very welcoming, and like a good waiter, unobtrusive but always available.
The flat:
Was right on top of the tube, which was very convenient (don't worry, no noise),
Very close to a nice Bakery (great for that morning croissant),
On top of a small supermarket - convenient,
Close to a good blend of restaurants (ah, but everyone in France smokes which tends to destroy the dining experience - the smell is everywhere),
Close to the main international train station (30 mins walk, 15 mins cab, 15-30 mins tube),
Has everything you need to cook up a storm, and
Tastefully decorated and uncluttered.

We really enjoyed our stay and we're sure you will too.
