Catherine's flat is lovely. It is centrally located, close to many of the sites (you can walk to Notre Dame, Hotel De Ville, and the Bastille) and across the street from a beautiful church and museum. There is a grocery store a block away and many cafes, bars,and restaurants within a five minute (or less) walk. And if you don't want to walk there are two train stations within two blocks (you are close to three different train lines). I didn't get to meet Catherine, but she was super responsive and flexible allowing me extend my stay last minute. The place is cute and truly has everything you need including a dishwasher and washing machine. It's a beautiful building with modern appliances, but with a charming Parisian feel. There is a lovely balcony for a sunny breakfast or drinks and there is a lift, which I hear is a rarity in Paris! I would highly recommend the flat. This was my first trip to Paris and I feel as if I stumbled upon a gem. I will definitely be booking this flat again!
