I would recommend Franck's place. It's a small, but very clean and modern apartment. The beds were very comfortable and there is a great little café downstairs for your morning coffee and a bite to eat, or evening drink before walking just a few minutes round the corner for restaurants for dinner. The "local" feel is very nice away from the tourist centres, but only a few minutes walk from the metro into the centre of Paris. I would definitely stay there again on another trip to Paris. It is fairly quiet, although you can hear footsteps above and hear the trains until quite late, but we didn't find that a problem.
