Julien and Maroussia are brilliant hosts. They make you feel very welcome and at home, they had even left a great little goodie bag of lovely food and wine. An extra star for that! Their place is absolutely amazing. A lot of space, nice and clean, an outdoor space which was great in a big city. It also had a great view with the Eiffel Tower in the horizon.
Belleville is a great area with everything available and that you would need like shops, restaurants etc. I highly recommend their place. I would stay there again if I came back to Paris.
