I stayed at Alex’s place and it was great. About a 5 min walk to the Cathedral and less than a 100 feet to the square. Alex was kind enough to have our luggage stored because we arrived early. When we checked in he thoroughly went through the apartment showing us all the amenities. It was great to have a fan in the loft and if you open then windows at night you’ll be able to see the Eiffel Tower in the distance. Just be warned the stairs are narrow, but manageable. We had a great time and will definitely be coming back.
