You know the saying about "Location, Location, Location." Well, this place has got all three. Right on the river, on lovely Ile St Louis, and jst steps from Notre Dame, etc etc etc. Shops on the same block, and gelato a few doors down. Location.
The only thing that was a little difficult for us was the night-time noise on the street. Due to a horrible heat wave in Paris (all of Europe), we had to leave the windows wide open at night, and the sirens and street revelers never seemed to stop.
