Apartment definitely has a character, much roomier than a lot of Parisian apartments, interesting vinyl record collection which Arnaud kindly allows to use. Nicely equipped kitchen, we were surprised that how good was the toast type oven.
Perfect location - nice residential area, literally one step from metro station, great street market on Wednesdays and Saturdays. Apartment itself is very quiet, as it is located on the 4th floor and not facing the street. Very bright place.
We were not using AC, as with opened windows and a small fan we were feeling fine even when the temperature outside was +35 C. Skylights in the loft can be kept opened even when it is raining.
Just be aware that apartment is located on the 4 th floor without elevator, staircases inside the apartment quit steep and narrow.
We haven't meet our host, as Arnaud was out of town, but he was very responsive and proactive with necessary information (like how to check in and check out).
