Understand that, as with all big cities, Paris involves trade offs. You will not find this kind of bang-on view (and it is every bit as glorious as represented) in a traditional, Haussman-era building in one of the inner arrandissments (1-8)--for the simple reason that such high-rise buildings don't exist there. In other words, if you expect a great view FROM the building, but not OF the building, your expectations will be met.
The service and communication by Jean-Claude and his handler were flawless and top notch. The apartment itself is well equipped, A/C works (but keep the shudders closed in the afternoon as the windows face west and it will get very hot if you don't). There is a shower, but no tub and the combination washer/dryer is new and works well.
You have great access via Metro and foot to interesting neighborhoods (Bastille, Marais, the 12eme, Oberkampf and the charming promenade plantee).
Overall, I would say this is an exceptional apartment for a single or couple who has been to Paris before (perhaps even many times). You will be staying in the "real", not tourist, Paris--although the latter is easily accessible. This was a plus for us, but I can see how a first-time visitor might want to be in closer to the center where things are "prettier", more English is spoken (and prices for everything are accordingly higher). None of that is to say a first time visitor couldn't have a great time here. Just know this is not a tourist neighborhood. Bon chance!
