Valentin was a perfect host: he was flexible with our arrival, always quick to reply by text or though airbnb and ready to help us with any questions.
The apartment was great too, within minutes walking from the Sacré-Coeur and and metroline that takes you to the city centre. The place has everything you need when you want to stay longer than a weekend. The room had a good atmosphere and was clean.
I can recommend staying at Valentin's place!
