Amazing location exactly as described. The Metro St Paul station, and taxi stand, are directly in front of the building. Grocery, pharmacy and many places to eat just a few doors down. Extremely noisy until about 3am, but that is to be expected in a major city on a main road, with a cafe downstairs. Description of stairs is accurate- on 3rd floor with no elevator. This height makes for wonderful people-watching from windows. Small bedroom (twin mattress) on lower level has very soft mattress. Up an extremely narrow and winding staircase to another “bedroom.” Not really a room. More like a bunk you might make in your college dorm. Double mattress covers entire floor. Ceiling about 4 feet above your head. Bad for adults but my teen loved it. Soft mattress there. On opposite side of flat is the “master “ bedroom. Up a slightly wider set of stairs to a double mattress on a platform. About a 2 foot wide strip of floor to stand on. We felt like we were in a ship captain’s berth. Perfectly fine as long as you know what to expect. Very hard mattress in that room. Pull out sofa in living room extremely hard. Would be fine for a toddler or small child. No air conditioner (which is typical) but plenty of fans and we were comfortable. Perfectly functional kitchen. Extremely small shower (our stomachs would hit the lever and change the temperature) but a nice big tub. Clothes washer takes about 2 hours per cycle (typical for Europe) for a small load. Racks provided for drying. Grant was wonderful, prompt and helped us with some special needs we had. Location could not be better for visiting all of Paris using the Metro. Location location location. Just bring noise-canceling headphones.
