Andrea's flat is really great, beautifully decorated - with the wifi network named ottodix, it is what you might expect - located in a very lively and nice neighborhood but still quiet, since it opens up on a inner court. Andrea was not around but organized a friend to come over who was very nice, helpful and responsive to any questions I had. Even though Andrea was not there he was also extremely reactive and gave good advice for restaurants and cultural activities in the area. I will definitively try to come back there next time I am in Paris.
