The house is in a brand new development, so as you'd expect the whole place is spotless and new, to the point that next door is still an empty shell and the street has no signs. Location is about 40mins walk from Lille center or a reasonable taxi.
Marines communication is excellent, she is very responsive and willing to help.
My only gripe is that it wasn't clear from the initial description that there would be someone else living in the house at the same time, which was a bit of a worry as a group of guys going out for the Euros. However we were aware well before arriving and it turns out Nicolas is a top guy, we didn't even know he was there and he even gave us a lift into town on the day of our arrival to save us the taxi (not to mention leaving breakfast every morning).
Wouldn't think twice about staying again.
