We had a very pleasant stay at Carine's (3 adults).
She was very helpful from the beginning -directions finding the house, tips for our stay, immediate responding in every message.
The house was clean and tidy. We had everything that we have agreed for.
The location is perfect for someone who wants to live Paris as a resident. Two steps from Sacre-Coeur, quiet at night but with many options in case you want a night life.
I definitely recommend it.
