I stayed here with a friend on a short getaway to Paris The location is fantastic. Very easy access from Gare du Nord (walkable) and also central to pretty much anything and everything you are likely to want to do and see for your trip to Paris.
The apartment is as pictured, cute and quaint, lots of natural light. It is in a secure building through multiple doors requiring a code + fob. We felt very safe. The beds were comfortable and the shower provided plenty of hot water. We didn't cook, but it appears there would be pans and a stovetop should you want to eat in.
We had a significant issue with check in but Viviana was very apologetic and as soon as that was resolved we were able to enjoy our time very much. I would recommend this stay for people traveling with friends or a couple without children who want to be central to everything and are able to do stairs comfortably.
