Guillaume’s apartment is as advertised — bright and spotless. Quiet, comfortable, well-equipped and in an excellent location. I would stay again.
The one issue we had was that while there is nearby parking available, the host texted us the morning of to let us know that certain sections of Paris, including where the apartment is located, would be blocked to vehicle traffic. In and of itself that is not an issue, but they also did not help us out at all in terms of offering a suggestion as to where we could / should park to take the metro to the apartment - we were left to figure that out ourselves on the fly.
