The seventh arrondissement may be the most popular part of Paris, it is also where you will be staying. There are many parks near and on the Seine, and everywhere you go within the area will be a short walk from the Eiffel Tower and the Champ de Mars. There are many small cafes lining the streets, immersing you in the culture, food, and language of France.
This area is the equivalent of the Gold Coast or Lincoln Park in Chicago. The area became the district of aristocrats in the 17th century, and it still possesses a large amount of wealth to this day. It is a very friendly and well-knit community. You will be very comfortable staying there.
