Benjamin went out of his way to have the place ready at short notice. It was just the place I needed. Quite, facing a nice courtyard. Adequate for one or a couple. There was enough of a kitchen to cook meals and a comfortable bed. It was also close to everything I wanted and being a few minutes from Rue Mouffetard was a real bonus. I would definitely stay there again.
(The place is small and has a steep stairway to the mezzanine bed and the shower is a bit tight, so larger or less able bodied people may want something else but it was fine for me.)
