I had a really great stay. The apartment was very picturesque, and I love that the window of the room faces the square. It was super conveniently close to the Metro (9- Voltaire) and also to the hip areas with bars and restaurants. For those who dance Kizomba, it's walking distance to Khao Suay on Rue de Lappe so that's another great perk.
Geoffroy was very responsive as a host which was fantastic since I booked the room rather last minute. The check-in was super easy even though he was not around and the place was clean and tidy. Even Suzy was super helpful when I accidentally locked my key inside (it was a great adventure). Having a washer/dryer was also super helpful during my stay.
I highly recommend this place and host.
