Caroline and her sister Nathalie were great hosts. Check in and check out were on time and communication was always fast and easy. They always attended to our requests on a quickly manner. We requested extra pillows and a mattress, and were promptly provided.
The apartment is indeed what you see in the pictures. There's a mention in the details about stairs, but the information that there is no elevator and it is on the fourth floor were in french. That was an issue at our arrival and departure since we had big and heavy luggage. But if you are traveling light it shouldn't be a problem.
There were a bit of cat fur here and there.
The apartment has heating and that was handy since the weather was very cold during our stay, with lots of snow. Still the place was warm and cozy.
