My wife and I stayed at the Hotel Square in mid June and were very happy. It was more $$ than we wanted to spend (we upgraded to a suite) but we figured this might be a once-in-a-lifetime experience. There are a few small markets close by for all of your needs and it is nestled by the river close to a residential area. The Eiffel Tower was about a 15 minute walk. The area felt very safe and the room was soundproof. The only negative is that it is out of the way a little, but nothing that the metro or train can't solve.
