I stayed in this room for three months as a student . The location is incredible and the neighborhood is beautiful-- you are steps from Place de la Bastille, Place des Vosges, Canal Saint-Martin and lines 1, 5, and 8 . However, if you are planning on spending more than just evenings in the space, it is not really comfortable . I am not sure how old the building is, but the room generates a lot of dust (the walls are a bit crumbly) and there is not much natural light . It is VERY small (college dorm room sized) . I would not plan on cooking much-- the kitchen is a converted cupboard and the sink is too small to wash dishes in without making a mess . Sometimes noises/smells (garbage) come in from the hallway, and you can hear the goings on of upstairs and next-door neighbors .
The bathroom is nice, and the room is a nice retreat after long days in the city . It can feel cozy if you don't spend too much time in it . Pierre is generally responsive to deal with concerns .
