I propose my sofa bed for one to rent. You’ll have the living-room for yourself.
It's a cozy well placed apartment: 20min to walk from Saint-Charles Station (5min by bus), 5min walk from Palais de Longchamps tramway and 5 min walk from the Friche belle de Mai (cultural and nightlife site).
As I have just moved in, it's not full (well) furnished (as you can see in the photos) but it has all the necessary. It's an economic and comfortable solution if you come visit Marseille for few days.
Sheets and duvet furnished.
