It´s a clean space and off the beaten tourist track but close enough to two metro stations and bus stops. Close to Pere Lachaise Cemetery which is a nice walk from there particularly in the Autumn and a bus away of Buttes Chaumont or Belleville Park. Stephane, co host, was really nice. I was there for a few days and came in only to sleep after a day of sightseeing, so I only used the bathroom, shower and my room. I´m not sure whether or not guests are able to use the terrace or the kitchen. For longer stays, I definitely recommend asking whether facilities are available. One thing to note is that check in is at 6pm onwards which is slightly later than most check ins in other Airbnb's. If you arrive early there's a place to leave your baggage in Gare Du Nord and it costs 7.5 euro to 9.5 euro depending on the size of your bags.
