This is a beautiful flat, very well located in the center of Paris. It is 1 minute away from the metro stations Châtelet, Les Halles, Réaumur Sébastopol, and Etienne Marcel. Very easy to access from the train stations or airports (ask me for instructions depending on which one you'll be arriving at).
You have everything needed: a bed, a small kitchen, bathroom, and space to store your things.
4th floor with elevator.
I can give you advice and recommend great places in the area.
