Great apartment! Looks like it has been renewed not long ago (lots of apartments in Paris seem pretty old, but definitely not this one). It was clean and the neighborhood of Batignolles has lots of nice bars and restaurants. It’s very close to the subway too. We didn’t meet Ylies since he was in a business trip but his sister came to give us the keys and show us around the flat and she was nice and helpful. Ylies was also very responsive with our questions. Overall a really good experience. I’d recommend it!
