My house is located close to the tramway stop Trois-Suisses 8' walking (then 22' to Lille Flandres).
Door to train station will take you a maximum of 45' should you miss a tram.
It's a very quiet neighborhood, you can easily park as well by the canal or directly in my street.
My staircase can be slippery especially downhill in socks. Keep that in mind !
