A space cleverly designed for maximum use of the footprint. Possibly once a garage. All purpose bathroom (shower) and comfortable bed Kitchen sitting area not well equipped beyond mini fridge and microwave, coffee machine and kettle - could use a hot plate. But dishes available. Wonderful windows and lovely mini-patio with seating for several guests. Quiet space. I did not find a heater and nights were occasionally chilly.
In a wonderful neighbourhood near the Gares du Nord and de l'Est.
