Justine's place is exceptionally lovely. She was really generous to let me and my friends stay in her lovely apartment for 2 nights while visiting for my friend's wedding in Paris. It is a very central location literally right next to the Arc de Triomphe. Had a little issue with internet but she was quick to help us resolve it. Again was a really beautiful place! Would love to stay there again if I were to visit Paris another time. My friends felt the same way. Highly recommend it :)
