Ced was an amazing host, he was on time, the place was clean and well equipped, Saint Paul metro station is just around the corner which is great, 10 minutes walk and you will be in the middle of le marais, the building is a little bit old so during summer time try not to open the windows answer leave it unattended for a long period of time, bugs might fly inside.
I recommend this place, specially for a long stay visit.
