We didn't meet Clementine but she was very responsive to messages.
Nice warm room, comfortable bed and nice wooden furnishings. There isn't a sink in the bathroom but there is one in the adjoining kitchen so not really a big deal. The toilet doesn't have a seat which is a bit odd.
Walking distance to Gare du Nord, which is useful if you're coming on the Eurostar, and some nice Indian restaurants nearby. Did feel a bit far from the Centre though.
All in all good experience staying at Clementines place.
