Its a great position - especially for Bastille, Place de voges and Père Lachaise. 3 local metro stations, good cafés and restaurants.
To our mind much smaller than photos suggested so 'cosy' should act as a warning!
It is very cluttered as most of marcella's possessions there (at tge moment?) so you have to live out of your suitcase. You may nit mind this and for us the positives of a comfortable bed and a good music system compensated.
