Lou is very responsive. Even though I've never met her in person but I met Paul, her brother who is very kind and helpful as well. There are a lot of dust but I think the city is generally very dusty. The area is quite dodgy at night. It's okay in the day. Just try to get home before the sky is dark.
The location is within walkable distance to Gare Du Nord and it's pretty convenient as there are many cafes around, and you can take the metro to most of the attractions.
