We had a wonderful time at at Christine's place in Le Marais. The location is great, very close to the Seine, perfect for a run or walk along the river and to many of the major landmarks. From her place, we walked to Notre Dame, the Luxembourg Gardens, Pantheon and Louvre, as well as to the Eiffel Tower (about an hour walk) where we enjoyed the gorgeous views of Paris along the way.
Beyond it's wonderful location, Christine was amazing. She provided excellent advice and recommendations for cafes and restaurants. We especially loved L'Avili for Corsican food and Le Voltigeur for cappuccinos, amazing quiche and croissants. If we find ourselves lucky enough to go back to Paris, we would love to stay there again!
