The apartment is really cool, lots of light, lots of air, and a great use of space. Be warned that the ceilings upstairs are quite low -- I'm only 5'5" (165cm) and I had to crouch -- so it's not ideal for really tall people! The neighbourhood is fairly quiet, which I enjoyed, and Buttes Chaumont park is very nice to have nearby.
We barely met Stephy, but she seemed very nice and communication before we arrived was very easy. Our arrival/meet-up did not go as planned and was a bit inconvenient, but overall this was a good AirBnB experience.
