This was the best apartment in Paris. Book it, if it is available. It is literally 5 minutes from the Notre Dame and about 7-8 minutes from the St. Michel metro stop. There is actually another stop closer to the apartment, but it is not a main metro line. However, we downloaded a Paris metro app which showed us exactly which routes to take using that closest stop. The apartment is very clean and in a very quiet and safe area. There are plenty of food options and supermarkets in the area. It is close to so many major places- we walked to the Louvre, Notre Dame, Pantheon (with a toddler!) and there is even a view of the Eiffel Tower only 2-3 minute walk from the apartment. It is on the 3rd floor (for USA or 2nd for Europe as they do not count the ground level as the first floor), but has an elevator if you are concerned about luggage. The apartment was a great size for a couple and the bed was very comfortable. There is even a pull out in the living room and a clothes washer. Julien was a great host. He met us at the metro stop, and left a very comprehensive guide about Paris. Again, I would highly recommend staying in this apartment to anyone.
