Matthieu and his family were very welcoming and friendly. He showed us around the apartment and had prepared some documents with local restaurants etc. that might be of interest. The apartment was well-equipped and comfortable. Belleville was a good quartier to call home. It is a 30-40 minute walk to, say, Notre-Dame, so Belleville is pretty well situated. And we were right beside the Métro. This was a very good stay.
