Joseph's apartment is in a great area. Within walking distance to everything!
As for the host - I couldn't have asked for any more! Joseph was kind enough to take me on a walking tour and allowed me to see so much more than I would ever have on my own. Hidden gems known only to true Parisians. His knowledge of the history of Paris and Europe at large is impressive and makes for really interesting conversation and insights.
I can't recommend a stay at Joseph's highly enough. I won't hesitate to stay at his place again on a return trip to Paris.
