Beautiful flat, very tastefully decorated - made me wish I lived there permanently. The area is very vibrant and might look a bit rough at first glance, but the local people we interacted with were all lovely and we had no problems at all, any time of night or day. Good access to public transport, an easy walk from Gare du Nord if arriving by Eurostar. Thanks Julien for the local tips, which made it easy to get orientated.
