Yann's place was in the perfect location - right near the Sacre Coeur and metro! On the same street there was a supermarket which was helpful. We stayed in summer (early July) and it was quiet hot inside. Yann was very easy to communicate with and when one of the blinds broke he was very willing to come and fix it asap. Apartment is basically one room but perfect if you don't plan on spending much time inside.
