Overall a small but cozy apartment for whoever needs a place just to rest while exploring Paris. Ideally not a place to be selected for a longer stay in Paris.
The location perfect (really close to the metro) and during the day, a busy and safe neighborhood. During the night the area gets quieter and in combination with the dark and old building, could lead someone to feel insecure.
There is room for improvements in the apartment with the most important ones being the smell and the door locker in the bathroom, but also the tap of the Kitchen sink.
