Nicolas’s apartment is a bit small, but very nice, clean and has everything you need. It is close to the Métro and only a few minutes walk from the Arc de Triumphe and Champs Élysée, you can even walk to the Eiffeltower. Keep in mind that you share the apartment with Nicolas and he will also be home, so maybe bring earplugs for sleeping, because you can hear everything (the TV, opening/closing doors, talking, etc.) through the walls. Other than that it‘s a really nice, central place for spending a weekend exploring Paris.
