We (family of 4) staid here for four nights and had a great time. The apartment on the fourth floor is beautiful and very clean. A taxi stand and a bus stop for (#26, 42 and 43) right in front of the building and 3 subway stations (#2, 7 and 12) nearby make getting around very easy. We skipped public transportation for the most part as the apartment's central location puts "all" the Paris sights within walking distance.
Anna was very helpful and check-in/check-out were a breeze. I highly recommend Anna's apartment and would definitely stay there again.
