Absolutely fabulous modern pristine space. Celine was so kind as to work with my early arrival time on a Saturday morning and greeted me to show how to get in/out and around the apartment. Very quick responses and helpful at all times. My friend and I were pleasantly surprised with coffee/milk, bread, snacks, water, etc. in the studio upon arrival. She has all of the amenities you could ask for including a good hair dryer, iron, large mirror closet so you can make sure you look great going out on the town in Paris ;) and fridge/stove/etc. if you needed it. She also has a nice suggestion book ready for you and was happy to share some of her advice on where to go.
The studio is right near a Metro stop and is walk-able to many things. There is even a Velib bike rental station just a short walk down the street that we used. Plenty of cafes, boulangeries, grocery store, and shopping are very close as well.
We were so happy with our choice to stay in Celine's gorgeous studio and thankful for her kindness. I would stay again the next time I come to Paris.
