Even though we didn't meet Mathieu during our stay there, we exchanged messages whenever we had a question and he actually gave us some tips on what to do there and was always willing to give us all the info that we asked for. The apartment is really just 2-3 mins away from the city center and from the river. There are even two small markets near the area where we stayed, a bakery, and bus stations. We found the room clean and we had everything at our disposal. We had a really nice time there!
