We had a great stay at Catherine's flat. It is well located on the second floor of an apartment building not too far away from the Montparnasse train station. It is small, but very cosy and clean, it is well equipped and personal, you can see that it is not only an airbnb but that it is lived in, which we appreciated. It has a double bed and a mattress in a separate room for a third person, a dining room table to eat at and an equipped small kitchen and a bath with a bathtub. It is a great place to stay at if you want to go explore everything that Paris has to offer. It is possible to arrive and access it at various times of the day independently of the owner, due to a code at the entrance door and a deposited key. Catherine was also very flexible with our departure time, allowing us to leave our luggage until the afternoon. We fully recommend her flat.
