Mario and Camille were awesome! We arrived and immediately Mario gave us a run down of the city and things that may be of interest. They also created walking tours that orient you throughout the whole city- we did them all! It made our exploring really easy and the way the tour takes you through the city brings you to unreal view of the Eiffel Tower! That was insane.
As for the apartment: 1.5 blocks from the main metro, extremely central and beautiful! We absoltuely loved it! Very clean as well. I would recommended it to anyone and would love to stay there again.
