Le Marais would have to be the best place to stay in Paris. Everything in walking distance. Lovely apartment, but not very clean, I had to wash the floors and the kitchen benches, make the bed, move all of her clothes from the wardrobe in the bedroom to a wardrobe by the front door, which she had wanted me to put my clothes...we were staying there for 5 and a half weeks, I thought it reasonable that we would have our clothes in the bedroom.
This was the first time that they had airbnb'd their apartment, so we all learn. Basically we loved the apartment and the area, hated leaving and wish Lihong well in future rentals!
