Josephine (the host) is a very nice woman. She was at the apartment to meet me on a Sunday after I was a couple of hours late arriving. She is also very hospitable. I stayed for two weeks and she prepared two dinners for me and the the other guest. Dalibor (who manages the reservations) is very responsive and also great.
The room is simple but has everything a person would really need (door that locks, desk, full sized bed, closet with hangers, hamper, etc.).
The neighborhood is good with plenty of nice restaurants, cafes, and bars. It is only about a five to ten minute walk to place de la République, which is a major train station with many lines.
