Alexandre is a great host, prompt, understanding and great communication.
The apartment is much better than it looks in the pictures, so much bigger too and the living areas face a quiet courtyard whereas the bedrooms face the street where you can watch people going about their daily business.
The area is so central. Sentier really is the heart of the city and you can easily reach almost anything on foot. The closest train is a mere 150m from the front door.
I definitely recommend
