Les Cocottes by Christian Constant was a cute and delicious little restaurant we found one night.
Musée de l'Orangerie is my favourite museum in Paris! The floor to ceiling Monet Water Lilies are incredible. Musée Marmottan Monet was also a wonderful one.
Early morning walks along the Seine are wonderful, of course! It also felt quite romantic to walk along the streets in the evening and pick a little restaurant based on what caught your eye in the moment, rather than strictly following reservations.
