We stayed at Wacyl's place for three nights in May and loved the space (clean, comfortable, light-filled during the day) and the location (right at the end of Rue Mouffetard, walkable/bikeable from many of the big Paris sites). Great communication leading up to our arrival including foolproof instructions for getting into the apartment. Pack light for the six floors of stairs but it's worth it for the great views from the balconies at sunset. :)
