The location cannot be understated! This island is seriously the most perfect place if you want to stay on the “safer” side of Paris but literally feel like a Parisian. It is a 5 minute walk to the Notre Dame and a 5-10 minute walk to the metro depending on which stop you want to take. The bridge across the Seine has plenty of singers and musicians to just get a glass of wine and listen to at night. The local small shops in the area were great, with everyone able to communicate easily with us. We were 2 small American girls and felt completely safe at night here as opposed to the Eiffel Tower area which was much more high traffic and not as well lit. We did have a hiccup where we were locked out of the apartment, since once the door shuts it will automatically lock. But the owner was quick to being able to contact the neighbors to shimmy the lock open. We are coming back to Paris in a few days and are hoping to stay again!
