Ivanna and Claude are such a great hosts.
I think It's the nicest experience so far in AirBnb for me. I booked the room for 4 nights for mom and me. We checked-in around 10 pm and they were very understanding with our delay. Every morning We received a breakfast and recommendations of places from them.
The room was tidy and clean. A great location, Sacre Cour is only 15 min by walk, nice restaurants and bars and three train stations very close as well.
If you want to spend a nice stay in Paris, you should book their room.
