I stayed in Sarah's room while she was away, and was hosted by her sister. The place is really cute and airy, and in a nice, residential area, perfect for if you wanna get away from the main touristy center of Paris. Everything was clean, tidy, good communication with the host, etc. It's a railroad-style apartment (so someone has to walk through the room to get to the bathroom), but it wasn't any inconvenience because she was really sweet and respectful about it.
