Couldn't have been much better.
The place was exactly as advertised. Relatively small & simple, but clean with a good view over Paris. (A 4* hotel room would be just half the size though.) Olivier was super friendly. Pick up of the keys went swiftly, accompanied by a nice chat.
I have stayed in this area of Paris a couple of times before. Located almost in the same building is a big shopping mall, which hosts a large variety of shops including a supermarket with good prices. Also the metro is just around the corner.
I would definitely recommend this place.
