I don't know this hotel, it's not in my favorite location, and looks pricey.

a better price (DBL 183 Euro) for this hotel.
I recently booked Novotel Tour Eiffel **** on priceline.com for $100. It's the former Nikko, nothing special, but O.K. You should start bidding with $80 or so.
Liked Villa Alessandra 17th Arr., 220Euro. and also Hotel Lennox St. Germain. Both are in nice, interesting areas.
