Didn't meet Sébastien, but he was on point with communicating and we figured out a key exchange that worked for both of us. He even said that I could stay the night before if I needed to! The room was clean and the balcony is great! He supplied a chocolate bar, a large water, and fresh towels. I ended up going out with his roomate one day and he introduced me to a few of his friends. The apt is close to the Metro and walkable to Belleville, which you should definitely check out during your stay. Great value, highly recommended!
