This is a clean flat in a central & convenient part of Paris near the Gare Du Nord train station (it's pretty easy to catch trains to and from the airport). Lars lives across the hall and so is quick to respond to any questions. The one downside of the place is that it can get loud. The door to the hallway doesn't block out much noise and there is a nightowl living on the floor above. Our first night there it sounded like they were doing a complete rearrangement of their furniture!
Aside from that and not having a coffee maker, we really enjoyed our stay, especially walking along the nearby canal.
