One of the best locations for all my favourite places in Paris - The Marais, Place Vosges, Centre Pompidou etc. Tip: Sign up to the app for renting Electric Pushbikes/ scooters and you can use them to be at Notre Dame in 10 minutes from the apartment. The place itself is super cool and the cafes are just fab closely. Go to Merci (1 minutes walk) for boiled eggs and soldiers breakfast amongst other things. The bed is very comfortable and on a split level to the main living room. Great water pressure in the shower and the kitchen has a hob and kettle. Typical gorgeous Paris windows to open and relax in the living room. We had excellent communication with Yves-Laurent and while he washout of town, his friend Slim was very kind and friendly in welcoming us to the place.
The flat is 4 flights up without a lift as mentioned and can get tiring after a long day prancing around Paris and if you are lazy like me. Also the ladder steps going up to the bedroom are really not for older people and one has to be a bit careful not to hit ones head on the slanting roof ceiling. Basically - I loved the apartment and will return.
