I loved staying at Andrée's studio. It is cozy, clean, quiet and have the amenities you need for a comfortable stay. Location is also very good: 15 minutes walk from the Cacre Couer or Mouling Rouge!! Also, very easy access to buses to different places of the city. Communiction was also very efficient, and the fact that we could leave our luggage before checking-in and after checking-out was a huge plus!
I would definitely recommend staying at Andrée's studio and would certainly stay there again if I go back to Paris someday.
