Sebastien and his roommates were welcoming and cordial, yet gave me my space. I have no reservations to recommend staying with them. The place is as described and pictured, an urban setting on a buzzing street with plenty of options of restaurants and bars nearby (and to me, some of the best options were the closest ones!).
For future guests, I'll add the tip that the mattress on the bed was very firm, knowing some people enjoy that and some do not.
