we experienced a wonderful and stay at his place. the room was overall very comfortable without any problems as well as Gaspard, the host, was so warm and helpful to us on everything.
in particular, we likes:
the location, quite close to 2 metro stations and couple of bus stations.
the bed, comfortably soft and large for 2.
the bath tab, very clean and large enough to get relaxed.
on top of that, we saw him often in the apartment building during the stay, which made us feel comfortable and secured.
lastly, we accidentally rocked the door with leaving the key inside the room at the last moment in the middle of carrying our luggage. we called him to ask bring us a space key to open. he kindly came to us so quickly and managed to get the airport without delay.
i definitely recommend to stay at his place when visiting paris, also we love to stay again when visiting there.
