Alice's apartment is my favorite crashing spot when I go to Paris (I am from the city living abroad).
This is the typical Parisian apartment, very clean, very cosy. Alice is a very nice host. All of this give me the feeling of staying at a friend's.
This area is my favorite in the city. It is central and one of the most trendy. You can walk two blocks North and enjoy the liveliness of Montmartre. You can walk two blocks South and experience the more poshy area of Saint-Georges, Haussmann, Opéra. But in the meanwhile you're in Pigale where you can expect some great evenings and nights.
Well, this is Paris I guess.
