The apartment is in a great location.
If travelling from the airport, Chatelet- Les Halles is only 100m from the apartment. This station is a major one, connecting you to many different lines. It is a central enough that all major attractions are within a 5-20min walk.
The apartment is later than most Parisian AirBnBs with a seperate kitchen and lounge of the main entry/Hall. The lounge, where the sofa bed is, can be closed off from the hall with glass French doors. All rooms have external black out blinds so the rooms are dark to sleep.
