We were 2 adults and 2 teenagers 10 and 13. The location is central (no parking but we didn't need it) a short walk from metro station and very close to Place de Voges. Quiet apartment with ikea furniture, nice beamed ceiling and old stone walls. it has surely it's charm. Only soap no other bathing gels.
Overall it was a very nice stay with no issues. Chirs was fast in communication. We never saw him.
The room where the teeners slept is really not a room but more like a garret, you have to be carefull not to hit the head.
The shower and the toilet are basically 2 "boxes" located each at the side of the corridor. In terms of privacy, you don't really have much. If you are in a family or very close friends it shouldn't be a problem.
As said a stay with no issue. thanks Chris
