The location is perfect - in the center of Paris (next to Triumphal arch), and 2 metro stations near the apartment, which allows you to easily get anywhere . Neighborhood (also Metro) is safe. There are Bars, Restaurants, Grocery stores and Shops near the apartment.
We stayed 4 persons (2 adults, 2 children) in apartment - space was enough for all of us.
In my opinion - best price-performance ratio for this deal!
