The apartment is beautiful and of historical value. Location is near to the main Gare De Lyin station which make travelling to other cities easier. There are supermarket near the apartment and a convenient store (Picard) which sells all kinds of instant food (heat up by microwave) which is good if you are travelling on a budget.
Though the wooden floor may produce noise when walk on this, I feel it all right as the apartment is more than 100 hundreds old so as expected.
