Our stay at Catherine's was very nice. The flat has a perfect location (5 minutes walking from Bellevile or Goncourt metro stations). It's in a quiet little street. The room is very cosy with a big and comfortable bed. The flat itself has a nice 'artistc soul' and is full of books, props and other decorations which is fascinating. The only thing is that the building is a block of flats and none of the doors inside have names nor numbers on them, so I think it would be helpful if you asked about it before your arrival. We had a bit of a problem figuring which one to knock. But apart from this, we had a great time and Catherine was a nice host, she explained everything to us and even invited us for her spectacle!
