The apartment is just steps away from Palais Royal, Louvre Museum, and Opera house. It is right in the heart of the Opera area, one of the most active and enjoyable neighborhoods in the city. The cafes are lively and the multitude of restaurants and bistros are excellent (mostly Japanese fare, but you can find other foods as well). Bakery around the corner - where you can buy a freshly baked baguette or croissant - and Monoprix (grocery store) 2 min walk away. The metro is just down the street for easy access to all of Paris. Many tourist agencies are within a 2-3 min walking distance and easy to go for excursions as well.
