I just stayed for 1 week with my wife and 3 teenage girls (1st week of July, 2013) in 2 Executive Rooms in the new tower and it was FABULOUS ! If we ever get to go back to Paris, we WILL stay at this hotel again. It is in the best location in Paris, as we could walk to every monument, museum and historic site within no more than 30 minutes (from the Eiffel Tower to Notre Dame, you're right in the middle). It was truly a 5-Star experience! We only rode 1 bus and never had to use the Metro.
I had read some reviews that made me think twice about staying here and even considered changing hotels, but I'm glad I didn't. This is a BEAUTIFUL hotel and the staff could not have been any nicer, friendlier or more helpful. Our rooms were very large and extremely well-kept. The bathroom absolutely sparkled and everything in the room was clean, new and wonderful. My wife and 3 girls loved it as well. The breakfast buffet was great and the price was not shocking, as I had read from some others. We ate breakfast at a cafe twice and the price was comparable. If you want McDonald's, then you can get a cheap breakfast, but not at any decent hotel or cafe.
Don't be turned off by some of the reviews. They just don't fit this hotel.
