Booked the hotel trough (http://www.duquesneeiffel.com) which is not the official hotel website, but got a nice rate (172 EUR for the room / night) compared to other servies. breakfast is additional EUR 12 but had a nice range and fresh pastries, tea, coffee, ham, scrambled eggs and cornflakes.
Our superior Room was No. 35 which had a great view to the Eiffel Tower out of the window. As rooms in paris are always quite small, the size was as expected. bed was comfortable and shower/toilet were clean and modern.
The location of the hotel is great, about 10 minutes walk from the eiffel tower away. Athough the hotel is directly at the street, there was no noise inside the room.
Reception was very helpful (giving tips for restaurants).
Two ideas for improvements: There was just one small wastebasket in the bathroom but no one in the bedroom.
The blankets were quite thick, so night was quite hot.
Negative impression was the airport shuttle (yellow van) which is arranged by the hotel but is an external company. The driver was very unfriendly and over 20 minutes to late, what is quite much if you have to catch a plane.
As in all big cities, there are tour buses, so we bought tickets for "open tour" which offers 4 different tours. If it's warm enought to sit on the on top (open bus area) it would be quite nice, else the windows are not so big an you won't be able to see much of the monuments.
Overall the hotel is definitely a good deal for a paris stay and I would recommend it.
