Jean-Baptiste was very helpful from the start. He responded quickly to all our questions and was kind enough to collect us at the station and explain how the tickets worked and how to best get to the apartment.
The apartment is located very near the metro station which is a big plus. A bigger plus is that it is located at the back of the building, which makes it very quiet even though it is near a big street.
We had a nice dinner at a (local, small) Italian restaurant nearby (I think it was called Dolphinos) and at a place near Rue Simonet - there are more little restaurants there. We also cooked at "home" and that went perfectly well as well. We had a place in the fridge for our groceries.
We had a very nice time and we will visit again the next time we're in Paris.
