A few weeks before our arrival Justine called to let us know that she had made a double booking but that she would make sure that we found another stay. She did, and we stayed in her mother's house, which is located perfectly in central Paris. We could even see the Eiffel Tower from the roof terrace. We had a short - but sweet - stay and Justine is super kind, very welcoming and a great host. She's easy to communicate with and very willing to help.
