Claudie's place is located less than 10 minutes walk from Jointville station (RER A) which is 25 minutes door to door from Gare de Lyon! Her flat is on the top floor and you can enjoy a rather incredible view of Paris from her living room or her roof terrace, even in winter!
Vintage decorated, the place looks and feels very homey and Claudie is a great host, with a friendly and jolly attitude.
The bed is more comfortable than mine, pillows are like clouds ; she leaves a bottle of water and a glass on the bedside table and a box of tissue is available in the bedroom.
I noticed that Claudie enjoys a glass of wine with a cigarette sometimes, but she is respectful and does so outdoors or at the window.
I highly recommend staying there if you're a solo traveler!
