The duplex is situated in the perfect position, in the heart of Montemartre and only minutes away from shops, restaurants and the Sacre-Coeur.
The flat is really nice and well furbished. Living room, kitchen and toilet upstairs and bathroom and two bedrooms downstairs. We were two couples and it worked perfectly for us.
The building doesn't have a lift, but we were travelling light so we were fine.
We haven't met Quentin and Constance in person but the communication was smooth and we found the keys straight away. As they were away, they also gave us a back up contact in Paris, in case we had any issue, which I think is very useful.
