Mathilde’s apartments are in a perfect location overlooking a busy square full of restaurants, cafes and bars - right in the heart of things. We were also able to stroll down to the Seine and all the usual tourist sights, I imagine that in the summer it would be delightful.
Unfortunately I’m unable to give this Airbnb a strong recommendation as there seemed to be an issue with the ventilation. Possibly due to a neighboring restaurant, the top three floors always seemed to be filled with frying odours and light smoke - all our clothes and luggage ended up smelling of food and covered in a thin film of grease. Unfortunately that spoiled it for us and we were always out of the apartment as quickly as possible - also not great after a few beers the night before.
