You couldn't ask for better communication or hospitality or a better location. It's a quiet street off of one of Montmartre's main streets, so you've got a tranquil place to sleep and make yourself breakfast but you're two minutes from great restaurants, bars, cheese shops, eclair shops, etc.--not to mention the Metro.
Pascal was very welcoming and even left fresh fruit and a bottle of wine as a welcome! His friend Fatiha was also very welcoming kind and explained everything about the apartment, including all the cooking equipment (there's a ton--you can make anything you want to eat at Pascal's).
The bed was also incredibly comfortable and the showers were excellent.
