I got in very early, and access to the apartment was granted as quickly as possible. With a pass-code lock on the main door to the building, key transfer was made much more easy.
The place was clean and functional, and though the shower was a little awkward to get into, the place was great for a long weekend stay - Very close to great restaurants and walkable to the Louvre, and the noise from the street at night wasn't too bad either!
