We loved staying at Christelle's place!
It's well stocked with appliances and is in a super convenient location. It is close to the shops on Avenue des Champs-Élysées, has many great, small, local restaurants right across the street (try Bagdad Bistro!) and is near a Monoprix grocery store if you need any essentials.
The pull out sofa bed is also surprisingly comfortable!
If you are traveling from another country with a lot of electronics, don't forget to bring extra conversion plugs.
Please note that there is a office building nearby and when people enter, there is a beeping sound when the windows are open.
