Ava's apartment is truly the perfect location from which to explore Paris. It's walkable to both the main sights and Montmartre, in a vibrant neighbourhood with plenty of lively bars/restaurants. There was some miscommunication around check-in (Ava happened to have an appointment right as we arrived), but she did everything she could to not keep us waiting too long. The climb up to the 6th floor is not for those with low mobility. Other than that, the apartment has everything you'd need for a great stay.
