We stayed for 2 nights at this apartment and we enjoyed our time a lot. The apartment is on the top floor of a five storey building (there is an elevator). The interior is simple but you will have everything you need. As the location is very central the apartment is noisy even during the night if the windows are open (there is a fan provided). Bergere was very flexible both with check in and check out times. We asked her recommendation about dinner and breakfast places in the neighbourhood and she answered straight away. The Notre Dame is only a few minutes walk away.
Thanks to Bergere's place we got to know Paris from a very different perspective and could live even only for 2 days as locals do. We will definitely stay here again!
