Jean Francois's flat is truly charming. We enjoyed the old world feel and the bells of St Severin literally right outside the window. We started each day on the small deck enjoying our coffee and the sounds of the city waking below our feet. We used three of the sleeping options (the main bed, pull-out sofa & loft area) and each reported comfortable beds. The flat was well stocked and communication was straightforward. Know that the flat is up four flights of steep stairs (we actually appreciated that bit of extra exercise each day) with no elevator -- and that you really are in the middle of a busy part of the Latin Quarter. Noise can be an issue, especially at nighttime on the weekend (we just used earplugs). The central location is superb for getting around the city by foot or Metro and you are an easy Metro ride from Gare du Nord. We thoroughly enjoyed our time here.
