Not a very outstanding building from the outside, you might say, but it was frequently visited by most of the 20th-century artists, actors, writers and other people somehow connected with art and also used as an art studio. The tradition survives till today and many Parisian artists wish to have their studios located there to follow in the footsteps of the masters.
Even if the place is not open to the public, you can still visit it and imagine Pablo Picasso creating one of his masterpieces there. The best-known masterpiece that was created here is definitely Picasso's "Les Demoiselles d'Avignon".
The interior is not open to public.
