The location is pretty good, very close to the metro station and only couple blocks from Rue Montorgueil. The street is lined with restaurants, cafés, bakeries, fish stores, cheese shops, wine shops, produce stands and flower shops. We met up with Thibaud's father at the studio without any problems. He was very helpful, patient and friendly to explain all the questions we have. They also have guide books for restaurants, and the directions to the tourist attractions.
It's a walking distance to most of the attractions plus shopping area etc.
The taxi from the airport to the studio is around Euro 50 + which is not too bad as we didn't bother to drag our luggage to the Metro.
The studio is very simple and clean in a nice secure building. Thibaud is quite easy to get a hold by email or text.
