We stayed at Laurent place for three nights. He was friendly and easygoing with us, he gave us suggestion on where to go (bar, restaurant, taxi number...).
The place is conveniently located close to the train station and to the city center, we also reached the Expo very quickly with the tram.
The room is quite small and very basic (which is not a problem if you stay for a weekend or so) with no wardrobe. The bathroom is nice and clean.
