Overall very good. The apartment is cosy, clean and well equipped. The location is great (the Mulin de la Galette is just at the end of the road) and close to the subway (10 minutes walking to line 2 and 12) - consider that it is a pretty steep road from the metro stop, though. Minor remarks: it is a basement apartment, but there are windows facing outside anyway; both the double bed and the third single bed are foldaway beds, so when they are all open there is not much room left. Stephan was super nice and very easy to communicate with. I recommend staying in his apartment.
