We stayed at Isabelle's place for four nights, and it was just right for us. The location of the apartment is great, and so is also the host. Isabelle makes it easy for you to arrive and, as she is mostly at work all the time, we haven't seen her once in the apartment (but she made every effort to make us feel welcomed, including some croissants waiting for us). We made a huge part of our tour just walking, thanks to the great location. The room is bright and has window and enough space for two people. In my opinion it was a great desicion to choose Isabelle's place. The only thing to be aware of, is that is a smoker apartment. We smoke ourselves, so it was a benefit for us, but it can be not the right fit for someone else. To summarize - very recommended!
