I love staying in this area in Paris. The street market three days a week and Rue Mouffetard every day. RER to/from the airport is a couple of blocks from the apartment and the metro station just as close in the other direction. The apartment is just as described. No problems getting keys and into apt. on the first day. The apartment is very quiet day and night. No sounds from the neighbors and much less street noise than I'm used to at home.
I'd recommend this place for a great stay in Paris and would stay there again if we return to Paris.
