My girlfriend and I spent 4 nights in Paris and had an amazing time. We would really recommend this. The flat is in an excellent location and the interior is really cool. Bed is comfy, we had no issues with heating or noise.
The area around the flat is ideal for breakfasts and wandering around and it is conveniently close to public transport.
Vinciane and Franc are lovely hosts and the communication was excellent. Franc gave us plenty tips on how to get around and where to go, as well as some stories about the building itself.
All in all, everything exceeded our expectations and I would highly recommend this place to anyone looking for a convenient, affordable and unique place to stay.
