My place(35m2) is 2mins walk from Metro Quatre chemins (line 7). You can directly reach main touristic places (Opéra, Louvre, Chatelet, Le Marais, Notre Dame, Latin District, Chinatown, the docks)
Parc de la Villette and Cité des Sciences are at walking distance.
The neighborhood is changing, animated like east london. People are friendly, food and groceries are cheap for a Parisian district.
My place is easy to use. The bed and the sofabed are both comfortable.
