Really authentic flat with great location near to Sacre Coeur and Mouline Rouge. A lot of really nice places around where you can eat or buy croissant :)).
Flat itself was huge (comparing to a hotel room where I was staying two days after :)) and cosy.
Communication with David was smooth and quick. We didn’t meet unfortunately but he was happy to help anytime and provided us with a lot of useful tips.
Really recommend for staying in Paris!
