Olivier is an amazing host, fully deserving his superhost status. Self check in is an amazing option for late or delayed flights, the bed is really comfortable and the flat has everything to make your stay easy and enjoyable.
10 minutes away is Sacre Couer, with delicious breakfast place (hardware societe), downstairs there's a shop and same street contains several really good restaurants.
I'd stay at this place every time I come to Paris. it's truly amazing
