Flora's place is fantastic! I was in Paris for a month, half of which was by myself. I felt super safe and the apartment was incredibly quiet. It had everything I needed for a longer stay and was very clean. Flora was super helpful on check-in, showing us a map of the area with key places marked so we would know where to get groceries, hop on the metro and eat out. It was a 10 min walk to metro line 4 which gets you to most of the must see areas in the city and being 15 minutes from Gare du Nord made it really easy to take day trips out of the city. I cannot recommend this place enough!!
