Location, location, location. When you think Paris, this is it. Overlooks the street in Latin Quarter, markets below. We had a lovely time walking for dinners and getting our day started. However, be prepared to wake up EARLY, as the markets/boulangeries start setting up about 6 am. Plenty of room for family of 5. It is convenient for the #5 Metro line, but seemingly had to make at least 1 transfer for any major attraction. Small grocery store to the north for various needs.
Be sure to try: Atelier 72 - Chez Poulpo; Au P'tit Grec; heard, but didn't try TournBride
Some restaurants are more touristy and overpriced than others, look around.
