I enjoyed my stay in Orsay Super Flat.
The flat is small but very well appointed. It has everything you might need of a 1-2 weeks stay, including: refrigerator, stove, microwave, tea kettle and coffee maker; pot/pan, plates, cups and utensils; an iron and ironing board; hair drier; full length mirror; shelves/storage space. There is also an tiny mudroom (separated from the main room with an actual door) - very convenient to take off and keep your shoes out of the main room.
The communication with the host was impeccable - can be reached at any time and responded to messages very quickly.
The location is great and close to everything.
