Staying at Claude's place was truly wonderful for my friend and I. She was incredibly responsive, kind, and professional as a host, and always got back to any of my messages within two hours or less.
She's got a cute rustic gem of an apartment in central Paris which is effectively walking distance to many great sights/museums such as the Louvre, Notre Dame, Saint Chapelle, and many more. Additionally, there's excellent shopping nearby, countless restaurants/cafes, so if you plan to visit Paris and will be out and about for most of the day, Claude's is an excellent option!
