I would really recommend the appartment of Grégoire and Cédric! It was a very nice place to spend our two days in the fantastic Paris, because it is nicely furnished, large, very neat and in a nice neighbourhood of Paris. A walk to the Bastille isn't that long and the Rue du Charonne is full of restaurants and nice bars. We only met Cédric and he showed himself a very good host (and gave us the recommandation to eat at Chez Gladine, a restaurant a couple of steps away from the house and a great place to eat indeed!).
