Ben's apartment is very charming. Quite spacious - more than enough room for a couple to coexist comfortably for short or long stays. The apartment is located in a great area - right across the street from the Sevres-Babylone Metro stop, and only about two blocks from La Grande Epicerie (a really fantastic supermarket). It's also within walking distance of all the major tourist sites; we had no problems walking to the Eiffel Tower (~40 minutes), the Louvre (20 minutes), Notre Dame (20 minutes), and many of the museums. Some people have mentioned the noise from the courtyard, but we didn't have any problems at all - yes, we heard the neighbors and the subway trains, but not to such an extent that either of us lost any sleep or were overly distracted by it. Overall, a clean, nice apartment; we would definitely stay here again if we're ever back in Paris.
