We had a great stay at Pauline's flat - it's small butclean, very well organised and it has everything you need. We felt at home :) The neighborhood is very lively at night, but we felt secure and we didn't hear any noises in the flat. The location is perfect - about 10 minutes from Notre Dame or Louvre and you can walk all the way to Eiffel tower - it is not that bad ;) All in all, I would definitely recommend staying at Pauline's flat!
