Very nice place!
You're so close to the Stade Charléty tram station, that getting anywhere with public transport is pretty easy.
Great home-base to visit all the city has to offer. Also great home-base if you're visiting an expo at versailles, since the tram from Stade Charléty goes all the way to Porte de Versailles, 30min ride, no changing needed.
For the room, its simple, its clean, its everything you expect, so pretty much perfect. Shower pressure could be a bit higher, but thats just me ;)
