Reasonable place as a home base. What you're getting is a private bedroom with a small balcony (1st floor) in a rather precarious nieghborhood (nothing too bad, there are definitely some worse off spots near Gare du Nord/Gare de l'Est). I could not access the kitchen even though the permanent inhabitant (Sarah's mother) was not there.
Sarah was quite responsive, and the price/quality ratio was reasonable given wild prices in Paris during NYE.
